-Notes on the Free Translation Project
-*************************************
-
-   Free software is going international!  The Free Translation Project
-is a way to get maintainers of free software, translators, and users all
-together, so that will gradually become able to speak many languages.
-A few packages already provide translations for their messages.
-
-   If you found this `ABOUT-NLS' file inside a distribution, you may
-assume that the distributed package does use GNU `gettext' internally,
-itself available at your nearest GNU archive site.  But you do _not_
-need to install GNU `gettext' prior to configuring, installing or using
-this package with messages translated.
-
-   Installers will find here some useful hints.  These notes also
-explain how users should proceed for getting the programs to use the
-available translations.  They tell how people wanting to contribute and
-work at translations should contact the appropriate team.
-
-   When reporting bugs in the `intl/' directory or bugs which may be
-related to internationalization, you should tell about the version of
-`gettext' which is used.  The information can be found in the
-`intl/VERSION' file, in internationalized packages.
-
-Quick configuration advice
-==========================
-
-   If you want to exploit the full power of internationalization, you
-should configure it using
-
-     ./configure --with-included-gettext
-
-to force usage of internationalizing routines provided within this
-package, despite the existence of internationalizing capabilities in the
-operating system where this package is being installed.  So far, only
-the `gettext' implementation in the GNU C library version 2 provides as
-many features (such as locale alias, message inheritance, automatic
-charset conversion or plural form handling) as the implementation here.
-It is also not possible to offer this additional functionality on top
-of a `catgets' implementation.  Future versions of GNU `gettext' will
-very likely convey even more functionality.  So it might be a good idea
-to change to GNU `gettext' as soon as possible.
-
-   So you need _not_ provide this option if you are using GNU libc 2 or
-you have installed a recent copy of the GNU gettext package with the
-included `libintl'.
-
-INSTALL Matters
-===============
-
-   Some packages are "localizable" when properly installed; the
-programs they contain can be made to speak your own native language.
-Most such packages use GNU `gettext'.  Other packages have their own
-ways to internationalization, predating GNU `gettext'.
-
-   By default, this package will be installed to allow translation of
-messages.  It will automatically detect whether the system already
-provides the GNU `gettext' functions.  If not, the GNU `gettext' own
-library will be used.  This library is wholly contained within this
-package, usually in the `intl/' subdirectory, so prior installation of
-the GNU `gettext' package is _not_ required.  Installers may use
-special options at configuration time for changing the default
-behaviour.  The commands:
-
-     ./configure --with-included-gettext
-     ./configure --disable-nls
-
-will respectively bypass any pre-existing `gettext' to use the
-internationalizing routines provided within this package, or else,
-_totally_ disable translation of messages.
-
-   When you already have GNU `gettext' installed on your system and run
-configure without an option for your new package, `configure' will
-probably detect the previously built and installed `libintl.a' file and
-will decide to use this.  This might be not what is desirable.  You
-should use the more recent version of the GNU `gettext' library.  I.e.
-if the file `intl/VERSION' shows that the library which comes with this
-package is more recent, you should use
-
-     ./configure --with-included-gettext
-
-to prevent auto-detection.
-
-   The configuration process will not test for the `catgets' function
-and therefore it will not be used.  The reason is that even an
-emulation of `gettext' on top of `catgets' could not provide all the
-extensions of the GNU `gettext' library.
-
-   Internationalized packages have usually many `po/LL.po' files, where
-LL gives an ISO 639 two-letter code identifying the language.  Unless
-translations have been forbidden at `configure' time by using the
-`--disable-nls' switch, all available translations are installed
-together with the package.  However, the environment variable `LINGUAS'
-may be set, prior to configuration, to limit the installed set.
-`LINGUAS' should then contain a space separated list of two-letter
-codes, stating which languages are allowed.
-
-Using This Package
-==================
-
-   As a user, if your language has been installed for this package, you
-only have to set the `LANG' environment variable to the appropriate
-`LL_CC' combination.  Here `LL' is an ISO 639 two-letter language code,
-and `CC' is an ISO 3166 two-letter country code.  For example, let's
-suppose that you speak German and live in Germany.  At the shell
-prompt, merely execute `setenv LANG de_DE' (in `csh'),
-`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
-This can be done from your `.login' or `.profile' file, once and for
-all.
-
-   You might think that the country code specification is redundant.
-But in fact, some languages have dialects in different countries.  For
-example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
-country code serves to distinguish the dialects.
-
-   Not all programs have translations for all languages.  By default, an
-English message is shown in place of a nonexistent translation.  If you
-understand other languages, you can set up a priority list of languages.
-This is done through a different environment variable, called
-`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
-for the purpose of message handling, but you still need to have `LANG'
-set to the primary language; this is required by other parts of the
-system libraries.  For example, some Swedish users who would rather
-read translations in German than English for when Swedish is not
-available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
-
-   In the `LANGUAGE' environment variable, but not in the `LANG'
-environment variable, `LL_CC' combinations can be abbreviated as `LL'
-to denote the language's main dialect.  For example, `de' is equivalent
-to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
-(Portuguese as spoken in Portugal) in this context.
-
-Translating Teams
-=================
-
-   For the Free Translation Project to be a success, we need interested
-people who like their own language and write it well, and who are also
-able to synergize with other translators speaking the same language.
-Each translation team has its own mailing list.  The up-to-date list of
-teams can be found at the Free Translation Project's homepage,
-`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
-area.
-
-   If you'd like to volunteer to _work_ at translating messages, you
-should become a member of the translating team for your own language.
-The subscribing address is _not_ the same as the list itself, it has
-`-request' appended.  For example, speakers of Swedish can send a
-message to `[email protected]', having this message body:
-
-     subscribe
-
-   Keep in mind that team members are expected to participate
-_actively_ in translations, or at solving translational difficulties,
-rather than merely lurking around.  If your team does not exist yet and
-you want to start one, or if you are unsure about what to do or how to
-get started, please write to `[email protected]' to reach the
-coordinator for all translator teams.
-
-   The English team is special.  It works at improving and uniformizing
-the terminology in use.  Proven linguistic skill are praised more than
-programming skill, here.
-
-Available Packages
-==================
-
-   Languages are not equally supported in all packages.  The following
-matrix shows the current state of internationalization, as of July
-2001.  The matrix shows, in regard of each package, for which languages
-PO files have been submitted to translation coordination, with a
-translation percentage of at least 50%.

-   Some counters in the preceding matrix are higher than the number of
-visible blocks let us expect.  This is because a few extra PO files are
-used for implementing regional variants of languages, or language
-dialects.
-
-   For a PO file in the matrix above to be effective, the package to
-which it applies should also have been internationalized and
-distributed as such by its maintainer.  There might be an observable
-lag between the mere existence a PO file and its wide availability in a
-distribution.
-
-   If July 2001 seems to be old, you may fetch a more recent copy of

-Using `gettext' in new packages
-===============================
-
-   If you are writing a freely available program and want to
-internationalize it you are welcome to use GNU `gettext' in your
-package.  Of course the GNU General Public License applies to your
-sources from then on if you include `gettext' directly in your
-distribution but since you are writing free software anyway this is no
-restriction.
-
-   Once the sources are changed appropriately and the setup can handle
-to use of `gettext' the only thing missing are the translations.  The
-Free Translation Project is also available for packages which are not
-developed inside the GNU project.  Therefore the information given above
-applies also for every other Free Software Project.  Contact
-`[email protected]' to make the `.pot' files available to
-the translation teams.

INSTALL

-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
-   The file `configure.in' is used to create `configure' by a program
-called `autoconf'.  You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
-     CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
-   If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

 Bison News
 ----------
 
-Changes in version 1.29a:
+Changes in version 1.49a:
+
+* Undefined token
+  The undefined token was systematically mapped to 2 which prevented
+  the use of 2 from the user.  This is no longer the case.
+
+* Undefined token
+  If yylex returned a code out of range, yyparse could die.  This is
+  no longer the case.
+
+* Error token
+  According to POSIX, the error token should be numbered as 256.
+  Bison extends this requirement by making it a preference: *if* the
+  user specified that one of her tokens is numbered 256, then error
+  will be mapped onto another number.
+
+* Large grammars
+  Are now supported (large token numbers, large grammar size (= sum of
+  the LHS and RHS lengths), large LALR tables).
+
+* The initial rule is explicit.
+  Bison used to play hacks with the initial rule, which the user does
+  not write.  It is now explicit, and visible in the reports and
+  graphs as rule 0.
+
+* Useless rules are actually removed.
+  Before, Bison reported the useless rules, but, although not used,
+  included them in the parsers.
+
+* False `Token not used' report fixed.
+  On a grammar such as
+
+           %token useless useful
+           %%
+           exp: '0' %prec useful;
+
+  where a token was used to set the precedence of the last rule,
+  bison reported both `useful' and `useless' as useless tokens.
+
+* Revert the C++ namespace changes introduced in 1.31, as they caused too
+  many portability hassles.
+
+* Items overflow
+  Bison no longer dumps core when there are too many items, it just
+  dies.
+
+* Token end-of-file
+  The token end of file may be specified by the user, in which case,
+  the user symbol is used in the reports, the graphs, and the verbose
+  error messages instead of `$', which remains being the defaults.
+  For instance
+     %token YYEOF 0
+  or
+     %token YYEOF 0 "end of file"
+
+Changes in version 1.35, 2002-03-25:
+
+* C Skeleton
+  Some projects use Bison's C parser with C++ compilers, and define
+  YYSTYPE as a class.  The recent adjustment of C parsers for data
+  alignment and 64 bit architectures made this impossible.
+
+  Because for the time being no real solution for C++ parser
+  generation exists, kludges were implemented in the parser to
+  maintain this use.  In the future, when Bison has C++ parsers, this
+  kludge will be disabled.
+
+  This kludge also addresses some C++ problems when the stack was
+  extended.
+
+
+Changes in version 1.34, 2002-03-12:
+
+* File name clashes are detected
+  $ bison foo.y -d -o foo.x
+  fatal error: header and parser would both be named `foo.x'
+
+* A missing `;' at the end of a rule triggers a warning
+  In accordance with POSIX, and in agreement with other
+  Yacc implementations, Bison will mandate this semicolon in the near
+  future.  This eases the implementation of a Bison parser of Bison
+  grammars by making this grammar LALR(1) instead of LR(2).  To
+  facilitate the transition, this release introduces a warning.
+
+* Revert the C++ namespace changes introduced in 1.31, as they caused too
+  many portability hassles.
+
+* DJGPP support added.
+
+* Fix test suite portability problems.
+
+Changes in version 1.33, 2002-02-07:
+
+* Fix C++ issues
+  Groff could not be compiled for the definition of size_t was lacking
+  under some conditions.
+
+* Catch invalid @n
+  As is done with $n.
+
+Changes in version 1.32, 2002-01-23:
+
+* Fix Yacc output file names
+
+* Portability fixes
+
+* Italian, Dutch translations
+
+Changes in version 1.31, 2002-01-14:
+
+* Many Bug Fixes
+
+* GNU Gettext and %expect
+  GNU Gettext asserts 10 s/r conflicts, but there are 7.  Now that
+  Bison dies on incorrect %expectations, we fear there will be
+  too many bug reports for Gettext, so _for the time being_, %expect
+  does not trigger an error when the input file is named `plural.y'.
+
+* Use of alloca in parsers
+  If YYSTACK_USE_ALLOCA is defined to 0, then the parsers will use
+  malloc exclusively.  Since 1.29, but was not NEWS'ed.
+
+  alloca is used only when compiled with GCC, to avoid portability
+  problems as on AIX.
+
+* When the generated parser lacks debugging code, YYDEBUG is now 0
+  (as POSIX requires) instead of being undefined.
+
+* User Actions
+  Bison has always permitted actions such as { $$ = $1 }: it adds the
+  ending semicolon.  Now if in Yacc compatibility mode, the semicolon
+  is no longer output: one has to write { $$ = $1; }.
+
+* Better C++ compliance
+  The output parsers try to respect C++ namespaces.
+  [This turned out to be a failed experiment, and it was reverted later.]
+
+* Reduced Grammars
+  Fixed bugs when reporting useless nonterminals.
+
+* 64 bit hosts
+  The parsers work properly on 64 bit hosts.
+
+* Error messages
+  Some calls to strerror resulted in scrambled or missing error messages.
+
+* %expect
+  When the number of shift/reduce conflicts is correct, don't issue
+  any warning.
+
+* The verbose report includes the rule line numbers.
+
+* Rule line numbers are fixed in traces.
+
+* Swedish translation
+
+* Parse errors
+  Verbose parse error messages from the parsers are better looking.
+  Before: parse error: unexpected `'/'', expecting `"number"' or `'-'' or `'(''
+     Now: parse error: unexpected '/', expecting "number" or '-' or '('
+
+* Fixed parser memory leaks.
+  When the generated parser was using malloc to extend its stacks, the
+  previous allocations were not freed.
+
+* Fixed verbose output file.
+  Some newlines were missing.
+  Some conflicts in state descriptions were missing.
+
+* Fixed conflict report.
+  Option -v was needed to get the result.
+
+* %expect
+  Was not used.
+  Mismatches are errors, not warnings.
+
+* Fixed incorrect processing of some invalid input.
+
+* Fixed CPP guards: 9foo.h uses BISON_9FOO_H instead of 9FOO_H.
+
+* Fixed some typos in the documentation.
+
+* %token MY_EOF 0 is supported.
+  Before, MY_EOF was silently renumbered as 257.
+
+* doc/refcard.tex is updated.
+
+* %output, %file-prefix, %name-prefix.
+  New.
+
+* --output
+  New, aliasing `--output-file'.

+  output file name. `-d' and `-g' do not change, they do not take any

+These notes intend to help people working on the CVS versions of

+
+* First CVS checkout

+Obviously, if you are reading these notes, you did manage to check out
+Bison from CVS.  For the records, you will find all the relevant
+information on:
+
+	http://savannah.gnu.org/cvs/?group_id=56

+The next step is asking the installation of all the missing files:

+
+	$ ./configure && make && make check
+
+At this point, there should be no difference between your local copy,

+* URGENT: Prologue
+The %union is declared after the user C declarations. It can be
+a problem if YYSTYPE is declared after the user part.
+
+Actually, the real problem seems that the %union ought to be output
+where it was defined.  For instance, in gettext/intl/plural.y, we
+have:
+
+	%{
+	...
+	#include "gettextP.h"
+	...
+	%}
+
+	%union {
+	  unsigned long int num;
+	  enum operator op;
+	  struct expression *exp;
+	}
+
+	%{
+	...
+	static int yylex PARAMS ((YYSTYPE *lval, const char **pexp));
+	...
+	%}
+
+Where the first part defines struct expression, the second uses it to
+define YYSTYPE, and the last uses YYSTYPE.  Only this order is valid.
+
+Note that we have the same problem with GCC.
+
+I suggest splitting the prologue into pre-prologue and post-prologue.
+The reason is that:
+
+1. we keep language independance as it is the skeleton that joins the
+two prologues (there is no need for the engine to encode union yystype
+and to output it inside the prologue, which breaks the language
+independance of the generator)
+
+2. that makes it possible to have several %union in input.  I think
+this is a pleasant (but useless currently) feature, but in the future,
+I want a means to %include other bits of grammars, and _then_ it will
+be important for the various bits to define their needs in %union.
+
+When implementing multiple-%union support, bare the following in mind:
+
+- when --yacc, this must be flagged as an error.  Don't make it fatal
+  though.
+
+- The #line must now appear *inside* the definition of yystype.
+  Something like
+
+	{
+	#line 12 "foo.y"
+	  int ival;
+	#line 23 "foo.y"
+	  char *sval;
+	}
+
+* Language independent actions
+
+Currently bison, the generator, transforms $1, $$ and so forth into
+direct C code, manipulating the stacks.  This is problematic, because
+(i) it means that if we want more languages, we need to update the
+generator, and (ii), it forces names everywhere (e.g., the C++
+skeleton would be happy to use other naming schemes, and actually,
+even other accessing schemes).
+
+Therefore we want
+
+1. the generator to replace $1, etc. by M4 macro invocations
+   (b4_dollar(1), b4_at(3), b4_dollar_dollar) etc.
+
+2. the skeletons to define these macros.
+
+But currently the actions are double-quoted, to protect them from M4
+evaluation.  So we need to:
+
+3. stop quoting them
+
+4. change the [ and ] in the actions into @<:@ and @:>@
+
+5. extend the postprocessor to maps these back onto [ and ].
+
+* Coding system independence
+Paul notes:
+
+	Currently Bison assumes 8-bit bytes (i.e. that UCHAR_MAX is
+	255).  It also assumes that the 8-bit character encoding is
+	the same for the invocation of 'bison' as it is for the
+	invocation of 'cc', but this is not necessarily true when
+	people run bison on an ASCII host and then use cc on an EBCDIC
+	host.  I don't think these topics are worth our time
+	addressing (unless we find a gung-ho volunteer for EBCDIC or
+	PDP-10 ports :-) but they should probably be documented
+	somewhere.
+
+* Using enums instead of int for tokens.
+Paul suggests:
+
+   #ifndef YYTOKENTYPE
+   # if defined (__STDC__) || defined (__cplusplus)
+      /* Put the tokens into the symbol table, so that GDB and other debuggers
+         know about them.  */
+      enum yytokentype {
+        FOO = 256,
+        BAR,
+        ...
+      };
+      /* POSIX requires `int' for tokens in interfaces.  */
+   #  define YYTOKENTYPE int
+   # endif
+   #endif
+   #define FOO 256
+   #define BAR 257
+   ...

+
+Yes, Automake currently used bison in Automake-compatible mode, but it
+would be fair for Automake to switch to the native mode as long as the
+processed files are distributed and "missing" emulates bison.
+
+In any case, the makefiles should specify the output file explicitly
+instead of relying on weird defaults.

+
+It's unfortunate that the native mode of Bison behaves in a less uniform

+want to fix it along with the documentation.

+
+I have no idea whether it qualifies as big or controversial, so I'll
+just summarize for you.  I proposed this change years ago and was
+surprised that it was met with utter indifference!
+
+This debug feature is for the programs/grammars one develops with
+bison, not for debugging bison itself.  I find that the YYDEBUG
+output comes in a very inconvenient format for my purposes.
+When debugging gcc, for instance, what I want is to see a trace of
+the sequence of reductions and the line#s for the semantic actions
+so I can follow what's happening.  Single-step in gdb doesn't cut it
+because to move from one semantic action to the next takes you through
+lots of internal machinery of the parser, which is uninteresting.
+
+The change I made was to the format of the debug output, so that it
+comes out in the format of C error messages, digestible by emacs
+compile mode, like so:
+
+grammar.y:1234: foo: bar(0x123456) baz(0x345678)
+
+where "foo: bar baz" is the reduction rule, whose semantic action
+appears on line 1234 of the bison grammar file grammar.y.  The hex
+numbers on the rhs tokens are the parse-stack values associated with
+those tokens.  Of course, yytype might be something totally
+incompatible with that representation, but for the most part, yytype
+values are single words (scalars or pointers).  In the case of gcc,
+they're most often pointers to tree nodes.  Come to think of it, the
+right thing to do is to make the printing of stack values be
+user-definable.  It would also be useful to include the filename &
+line# of the file being parsed, but the main filename & line# should
+continue to be that of grammar.y
+
+Anyway, this feature has saved my life on numerous occasions.  The way
+I customarily use it is to first run bison with the traces on, isolate
+the sequence of reductions that interests me, put those traces in a
+buffer and force it into compile-mode, then visit each of those lines
+in the grammar and set breakpoints with C-x SPACE.  Then, I can run
+again under the control of gdb and stop at each semantic action.
+With the hex addresses of tree nodes, I can inspect the values
+associated with any rhs token.
+
+You like?
+
+* input synclines
+Some users create their foo.y files, and equip them with #line.  Bison
+should recognize these, and preserve them.
+
+* BTYacc
+See if we can integrate backtracking in Bison.  Contact the BTYacc
+maintainers.
+
+* Automaton report
+Display more clearly the lookaheads for each item.
+
+* RR conflicts
+See if we can use precedence between rules to solve RR conflicts.  See
+what POSIX says.
+
+* Precedence
+It is unfortunate that there is a total order for precedence.  It
+makes it impossible to have modular precedence information.  We should
+move to partial orders.

+* Parsing grammars

+
+* Problems with aliases
+From: "Baum, Nathan I" <[email protected]>
+Subject: Token Alias Bug
+To: "'[email protected]'" <[email protected]>
+
+I've noticed a bug in bison. Sadly, our eternally wise sysadmins won't let
+us use CVS, so I can't find out if it's been fixed already...
+
+Basically, I made a program (in flex) that went through a .y file looking
+for "..."-tokens, and then outputed a %token
+line for it. For single-character ""-tokens, I reasoned, I could just use
+[%token 'A' "A"]. However, this causes Bison to output a [#define 'A' 65],
+which cppp chokes on, not unreasonably. (And even if cppp didn't choke, I
+obviously wouldn't want (char)'A' to be replaced with (int)65 throughout my
+code.
+
+Bison normally forgoes outputing a #define for a character token. However,
+it always outputs an aliased token -- even if the token is an alias for a
+character token. We don't want that. The problem is in /output.c/, as I
+recall. When it outputs the token definitions, it checks for a character
+token, and then checks for an alias token. If the character token check is
+placed after the alias check, then it works correctly.
+
+Alias tokens seem to be something of a kludge. What about an [%alias "..."]
+command...
+
+	%alias T_IF "IF"
+
+Hmm. I can't help thinking... What about a --generate-lex option that
+creates an .l file for the alias tokens used... (Or an option to make a
+gperf file, etc...)
+
+* Presentation of the report file
+From: "Baum, Nathan I" <[email protected]>
+Subject: Token Alias Bug
+To: "'[email protected]'" <[email protected]>
+
+I've also noticed something, that whilst not *wrong*, is inconvienient: I
+use the verbose mode to help find the causes of unresolved shift/reduce
+conflicts. However, this mode insists on starting the .output file with a
+list of *resolved* conflicts, something I find quite useless. Might it be
+possible to define a -v mode, and a -vv mode -- Where the -vv mode shows
+everything, but the -v mode only tells you what you need for examining
+conflicts? (Or, perhaps, a "*** This state has N conflicts ***" marker above
+each state with conflicts.)
+
+
+* $undefined
+From Hans:
+- If the Bison generated parser experiences an undefined number in the
+character range, that character is written out in diagnostic messages, an
+addition to the $undefined value.
+
+Suggest: Change the name $undefined to undefined; looks better in outputs.
+
+* Default Action
+From Hans:
+- For use with my C++ parser, I transported the "switch (yyn)" statement
+that Bison writes to the bison.simple skeleton file. This way, I can remove
+the current default rule $$ = $1 implementation, which causes a double
+assignment to $$ which may not be OK under C++, replacing it with a
+"default:" part within the switch statement.
+
+Note that the default rule $$ = $1, when typed, is perfectly OK under C,
+but in the C++ implementation I made, this rule is different from
+$<type_name>$ = $<type_name>1. I therefore think that one should implement
+a Bison option where every typed default rule is explicitly written out
+(same typed ruled can of course be grouped together).
+
+* Pre and post actions.

+Subject: YYACT_EPILOGUE
+To: [email protected]
+X-Sent: 1 week, 4 days, 14 hours, 38 minutes, 11 seconds ago
+
+The other day I had the need for explicitly building the parse tree. I
+used %locations for that and defined YYLLOC_DEFAULT to call a function
+that returns the tree node for the production. Easy. But I also needed
+to assign the S-attribute to the tree node. That cannot be done in
+YYLLOC_DEFAULT, because it is invoked before the action is executed.
+The way I solved this was to define a macro YYACT_EPILOGUE that would
+be invoked after the action. For reasons of symmetry I also added
+YYACT_PROLOGUE. Although I had no use for that I can envision how it
+might come in handy for debugging purposes.
+All is needed is to add
+
+#if YYLSP_NEEDED
+    YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen, yyloc, (yylsp - yylen));
+#else
+    YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen);
+#endif
+
+at the proper place to bison.simple. Ditto for YYACT_PROLOGUE.
+
+I was wondering what you think about adding YYACT_PROLOGUE/EPILOGUE
+to bison. If you're interested, I'll work on a patch.

-/* This file redirects the gettext functions (without prefix or suffix) to
-   those defined in the included GNU gettext library (with "__" suffix).
-   It is compiled into libintl when the included GNU gettext library is
-   configured --with-included-gettext.
-
-   This redirection works also in the case that the system C library or
-   the system libintl library contain gettext/textdomain/... functions.
-   If it didn't, we would need to add preprocessor level redirections to
-   libgnuintl.h of the following form:
-
-#    define gettext gettext__
-#    define dgettext dgettext__
-#    define dcgettext dcgettext__
-#    define ngettext ngettext__
-#    define dngettext dngettext__
-#    define dcngettext dcngettext__
-#    define textdomain textdomain__
-#    define bindtextdomain bindtextdomain__
-#    define bind_textdomain_codeset bind_textdomain_codeset__
-
-   How does this redirection work? There are two cases.
-   A. When libintl.a is linked into an executable, it works because
-      functions defined in the executable always override functions in
-      the shared libraries.
-   B. When libintl.so is used, it works because
-      1. those systems defining gettext/textdomain/... in the C library
-         (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer) are
-         ELF systems and define these symbols as weak, thus explicitly
-         letting other shared libraries override it.
-      2. those systems defining gettext/textdomain/... in a standalone
-         libintl.so library (namely, Solaris 2.3 and newer) have this
-         shared library in /usr/lib, and the linker will search /usr/lib
-         *after* the directory where the GNU gettext library is installed.
-
-   A third case, namely when libintl.a is linked into a shared library
-   whose name is not libintl.so, is not supported. In this case, on
-   Solaris, when -lintl precedes the linker option for the shared library
-   containing GNU gettext, the system's gettext would indeed override
-   the GNU gettext. Anyone doing this kind of stuff must be clever enough
-   to 1. compile libintl.a with -fPIC, 2. remove -lintl from his linker
-   command line.  */

-.TH ANSI2KNR 1 "19 Jan 1996"
-.SH NAME
-ansi2knr \- convert ANSI C to Kernighan & Ritchie C
-.SH SYNOPSIS
-.I ansi2knr
-[--varargs] input_file [output_file]
-.SH DESCRIPTION
-If no output_file is supplied, output goes to stdout.
-.br
-There are no error messages.
-.sp
-.I ansi2knr
-recognizes function definitions by seeing a non-keyword identifier at the left
-margin, followed by a left parenthesis, with a right parenthesis as the last
-character on the line, and with a left brace as the first token on the
-following line (ignoring possible intervening comments).  It will recognize a
-multi-line header provided that no intervening line ends with a left or right
-brace or a semicolon.  These algorithms ignore whitespace and comments, except
-that the function name must be the first thing on the line.
-.sp
-The following constructs will confuse it:
-.br
-     - Any other construct that starts at the left margin and follows the
-above syntax (such as a macro or function call).
-.br
-     - Some macros that tinker with the syntax of the function header.
-.sp
-The --varargs switch is obsolete, and is recognized only for
-backwards compatibility.  The present version of
-.I ansi2knr
-will always attempt to convert a ... argument to va_alist and va_dcl.
-.SH AUTHOR
-L. Peter Deutsch <[email protected]> wrote the original ansi2knr and
-continues to maintain the current version; most of the code in the current
-version is his work.  ansi2knr also includes contributions by Francois
-Pinard <[email protected]> and Jim Avera <[email protected]>.

- * Usage:
-	ansi2knr [--filename FILENAME] [INPUT_FILE [OUTPUT_FILE]]
- * --filename provides the file name for the #line directive in the output,
- * overriding input_file (if present).
- * If no input_file is supplied, input is read from stdin.
- * If no output_file is supplied, output goes to stdout.
- * There are no error messages.
- *
- * ansi2knr recognizes function definitions by seeing a non-keyword
- * identifier at the left margin, followed by a left parenthesis,
- * with a right parenthesis as the last character on the line,
- * and with a left brace as the first token on the following line
- * (ignoring possible intervening comments), except that a line
- * consisting of only
- *	identifier1(identifier2)
- * will not be considered a function definition unless identifier2 is
- * the word "void".  ansi2knr will recognize a multi-line header provided
- * that no intervening line ends with a left or right brace or a semicolon.
- * These algorithms ignore whitespace and comments, except that
- * the function name must be the first thing on the line.
- * The following constructs will confuse it:

- * The original and principal author of ansi2knr is L. Peter Deutsch
- * <[email protected]>.  Other authors are noted in the change history
- * that follows (in reverse chronological order):
-	lpd 1998-11-09 added further hack to recognize identifier(void)
-		as being a procedure
-	lpd 1998-10-23 added hack to recognize lines consisting of
-		identifier1(identifier2) as *not* being procedures
-	lpd 1997-12-08 made input_file optional; only closes input and/or
-		output file if not stdin or stdout respectively; prints
-		usage message on stderr rather than stdout; adds
-		--filename switch (changes suggested by
-		<[email protected]>)
-	lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
-		compilers that don't understand void, as suggested by
-		Tom Lane
-	lpd 1996-01-15 changed to require that the first non-comment token
-		on the line following a function header be a left brace,
-		to reduce sensitivity to macros, as suggested by Tom Lane
-		<[email protected]>
-	lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
-		undefined preprocessor symbols as 0; changed all #ifdefs
-		for configuration symbols to #ifs
-	lpd 1995-04-05 changed copyright notice to make it clear that
-		including ansi2knr in a program does not bring the entire
-		program under the GPL
-	lpd 1994-12-18 added conditionals for systems where ctype macros
-		don't handle 8-bit characters properly, suggested by
-		Francois Pinard <[email protected]>;
-		removed --varargs switch (this is now the default)
-	lpd 1994-10-10 removed CONFIG_BROKETS conditional
-	lpd 1994-07-16 added some conditionals to help GNU `configure',
-		suggested by Francois Pinard <[email protected]>;
-		properly erase prototype args in function parameters,
-		contributed by Jim Avera <[email protected]>;
