-Changes in version 1.49c:
+Changes in version 2.3a, 2006-09-13:
 
+* Instead of %union, you can define and use your own union type
+  YYSTYPE if your grammar contains at least one <type> tag.
+  Your YYSTYPE need not be a macro; it can be a typedef.
+  This change is for compatibility with other Yacc implementations,
+  and is required by POSIX.
 
-Changes in version 1.49b, 2002-08-12:
+* Locations columns and lines start at 1.
+  In accordance with the GNU Coding Standards and Emacs.
+
+* You may now declare per-type and default %destructor's and %printer's:
+
+  For example:
+
+    %union { char *string; }
+    %token <string> STRING1
+    %token <string> STRING2
+    %type  <string> string1
+    %type  <string> string2
+    %union { char character; }
+    %token <character> CHR
+    %type  <character> chr
+    %destructor { free ($$); } %symbol-default
+    %destructor { free ($$); printf ("%d", @$.first_line); } STRING1 string1
+    %destructor { } <character>
+
+  guarantees that, when the parser discards any user-defined symbol that has a
+  semantic type tag other than `<character>', it passes its semantic value to
+  `free'.  However, when the parser discards a `STRING1' or a `string1', it
+  also prints its line number to `stdout'.  It performs only the second
+  `%destructor' in this case, so it invokes `free' only once.
+
+* Except for LALR(1) parsers in C with POSIX Yacc emulation enabled (with `-y',
+  `--yacc', or `%yacc'), Bison no longer generates #define statements for
+  associating token numbers with token names.  Removing the #define statements
+  helps to sanitize the global namespace during preprocessing, but POSIX Yacc
+  requires them.  Bison still generates an enum for token names in all cases.
+
+* Handling of traditional Yacc prologue blocks is now more consistent but
+  potentially incompatible with previous releases of Bison.
+
+  As before, you declare prologue blocks in your grammar file with the
+  `%{ ... %}' syntax.  To generate the pre-prologue, Bison concatenates all
+  prologue blocks that you've declared before the first %union.  To generate
+  the post-prologue, Bison concatenates all prologue blocks that you've
+  declared after the first %union.
+
+  Previous releases of Bison inserted the pre-prologue into both the header
+  file and the code file in all cases except for LALR(1) parsers in C.  In the
+  latter case, Bison inserted it only into the code file.  For parsers in C++,
+  the point of insertion was before any token definitions (which associate
+  token numbers with names).  For parsers in C, the point of insertion was
+  after the token definitions.
+
+  Now, Bison never inserts the pre-prologue into the header file.  In the code
+  file, it always inserts it before the token definitions.
+
+* Bison now provides a more flexible alternative to the traditional Yacc
+  prologue blocks: %before-header, %start-header, %end-header, and
+  %after-header.
+
+  For example, the following declaration order in the grammar file reflects the
+  order in which Bison will output these code blocks.  However, you are free to
+  declare these code blocks in your grammar file in whatever order is most
+  convenient for you:
+
+    %before-header {
+      /* Bison treats this block like a pre-prologue block: it inserts it into
+       * the code file before the contents of the header file.  It does *not*
+       * insert it into the header file.  This is a good place to put
+       * #include's that you want at the top of your code file.  A common
+       * example is `#include "system.h"'.  */
+    }
+    %start-header {
+      /* Bison inserts this block into both the header file and the code file.
+       * In both files, the point of insertion is before any Bison-generated
+       * token, semantic type, location type, and class definitions.  This is a
+       * good place to define %union dependencies, for example.  */
+    }
+    %union {
+      /* Unlike the traditional Yacc prologue blocks, the output order for the
+       * new %*-header blocks is not affected by their declaration position
+       * relative to any %union in the grammar file.  */
+    }
+    %end-header {
+      /* Bison inserts this block into both the header file and the code file.
+       * In both files, the point of insertion is after the Bison-generated
+       * definitions.  This is a good place to declare or define public
+       * functions or data structures that depend on the Bison-generated
+       * definitions.  */
+    }
+    %after-header {
+      /* Bison treats this block like a post-prologue block: it inserts it into
+       * the code file after the contents of the header file.  It does *not*
+       * insert it into the header file.  This is a good place to declare or
+       * define internal functions or data structures that depend on the
+       * Bison-generated definitions.  */
+    }
+
+  If you have multiple occurrences of any one of the above declarations, Bison
+  will concatenate the contents in declaration order.
+
+* The option `--report=look-ahead' has been changed to `--report=lookahead'.
+  The old spelling still works, but is not documented and may be removed
+  in a future release.
+
+Changes in version 2.3, 2006-06-05:
+
+* GLR grammars should now use `YYRECOVERING ()' instead of `YYRECOVERING',
+  for compatibility with LALR(1) grammars.
+
+* It is now documented that any definition of YYSTYPE or YYLTYPE should
+  be to a type name that does not contain parentheses or brackets.
+
+Changes in version 2.2, 2006-05-19:
+
+* The distribution terms for all Bison-generated parsers now permit
+  using the parsers in nonfree programs.  Previously, this permission
+  was granted only for Bison-generated LALR(1) parsers in C.
+
+* %name-prefix changes the namespace name in C++ outputs.
+
+* The C++ parsers export their token_type.
+
+* Bison now allows multiple %union declarations, and concatenates
+  their contents together.
+
+* New warning: unused values
+  Right-hand side symbols whose values are not used are reported,
+  if the symbols have destructors.  For instance:
+
+     exp: exp "?" exp ":" exp { $1 ? $1 : $3; }
+	| exp "+" exp
+	;
+
+  will trigger a warning about $$ and $5 in the first rule, and $3 in
+  the second ($1 is copied to $$ by the default rule).  This example
+  most likely contains three errors, and could be rewritten as:
+
+     exp: exp "?" exp ":" exp
+	    { $$ = $1 ? $3 : $5; free ($1 ? $5 : $3); free ($1); }
+	| exp "+" exp
+	    { $$ = $1 ? $1 : $3; if ($1) free ($3); }
+	;
+
+  However, if the original actions were really intended, memory leaks
+  and all, the warnings can be suppressed by letting Bison believe the
+  values are used, e.g.:
+
+     exp: exp "?" exp ":" exp { $1 ? $1 : $3; (void) ($$, $5); }
+	| exp "+" exp         { $$ = $1; (void) $3; }
+	;
+
+  If there are mid-rule actions, the warning is issued if no action
+  uses it.  The following triggers no warning: $1 and $3 are used.
+
+     exp: exp { push ($1); } '+' exp { push ($3); sum (); };
+
+  The warning is intended to help catching lost values and memory leaks.
+  If a value is ignored, its associated memory typically is not reclaimed.
+
+* %destructor vs. YYABORT, YYACCEPT, and YYERROR.
+  Destructors are now called when user code invokes YYABORT, YYACCEPT,
+  and YYERROR, for all objects on the stack, other than objects
+  corresponding to the right-hand side of the current rule.
+
+* %expect, %expect-rr
+  Incorrect numbers of expected conflicts are now actual errors,
+  instead of warnings.
+
+* GLR, YACC parsers.
+  The %parse-params are available in the destructors (and the
+  experimental printers) as per the documentation.
+
+* Bison now warns if it finds a stray `$' or `@' in an action.
+
+* %require "VERSION"
+  This specifies that the grammar file depends on features implemented
+  in Bison version VERSION or higher.
+
+* lalr1.cc: The token and value types are now class members.
+  The tokens were defined as free form enums and cpp macros.  YYSTYPE
+  was defined as a free form union.  They are now class members:
+  tokens are enumerations of the `yy::parser::token' struct, and the
+  semantic values have the `yy::parser::semantic_type' type.
+
+  If you do not want or can update to this scheme, the directive
+  `%define "global_tokens_and_yystype" "1"' triggers the global
+  definition of tokens and YYSTYPE.  This change is suitable both
+  for previous releases of Bison, and this one.
+
+  If you wish to update, then make sure older version of Bison will
+  fail using `%require "2.2"'.
+
+* DJGPP support added.
+
+Changes in version 2.1, 2005-09-16:
+
+* The C++ lalr1.cc skeleton supports %lex-param.
+
+* Bison-generated parsers now support the translation of diagnostics like
+  "syntax error" into languages other than English.  The default
+  language is still English.  For details, please see the new
+  Internationalization section of the Bison manual.  Software
+  distributors should also see the new PACKAGING file.  Thanks to
+  Bruno Haible for this new feature.
+
+* Wording in the Bison-generated parsers has been changed slightly to
+  simplify translation.  In particular, the message "memory exhausted"
+  has replaced "parser stack overflow", as the old message was not
+  always accurate for modern Bison-generated parsers.
+
+* Destructors are now called when the parser aborts, for all symbols left
+  behind on the stack.  Also, the start symbol is now destroyed after a
+  successful parse.  In both cases, the behavior was formerly inconsistent.
+
+* When generating verbose diagnostics, Bison-generated parsers no longer
+  quote the literal strings associated with tokens.  For example, for
+  a syntax error associated with '%token NUM "number"' they might
+  print 'syntax error, unexpected number' instead of 'syntax error,
+  unexpected "number"'.
+
+Changes in version 2.0, 2004-12-25:
+
+* Possibly-incompatible changes
+
+  - Bison-generated parsers no longer default to using the alloca function
+    (when available) to extend the parser stack, due to widespread
+    problems in unchecked stack-overflow detection.  You can "#define
+    YYSTACK_USE_ALLOCA 1" to require the use of alloca, but please read
+    the manual to determine safe values for YYMAXDEPTH in that case.
+
+  - Error token location.
+    During error recovery, the location of the syntax error is updated
+    to cover the whole sequence covered by the error token: it includes
+    the shifted symbols thrown away during the first part of the error
+    recovery, and the lookahead rejected during the second part.
+
+  - Semicolon changes:
+    . Stray semicolons are no longer allowed at the start of a grammar.
+    . Semicolons are now required after in-grammar declarations.
+
+  - Unescaped newlines are no longer allowed in character constants or
+    string literals.  They were never portable, and GCC 3.4.0 has
+    dropped support for them.  Better diagnostics are now generated if
+    forget a closing quote.
+
+  - NUL bytes are no longer allowed in Bison string literals, unfortunately.
+
+* New features
+
+  - GLR grammars now support locations.
+
+  - New directive: %initial-action.
+    This directive allows the user to run arbitrary code (including
+    initializing @$) from yyparse before parsing starts.
+
+  - A new directive "%expect-rr N" specifies the expected number of
+    reduce/reduce conflicts in GLR parsers.
+
+  - %token numbers can now be hexadecimal integers, e.g., `%token FOO 0x12d'.
+    This is a GNU extension.
+
+  - The option `--report=lookahead' was changed to `--report=look-ahead'.
+    [However, this was changed back after 2.3.]
+
+  - Experimental %destructor support has been added to lalr1.cc.
+
+  - New configure option --disable-yacc, to disable installation of the
+    yacc command and -ly library introduced in 1.875 for POSIX conformance.
+
+* Bug fixes
+
+  - For now, %expect-count violations are now just warnings, not errors.
+    This is for compatibility with Bison 1.75 and earlier (when there are
+    reduce/reduce conflicts) and with Bison 1.30 and earlier (when there
+    are too many or too few shift/reduce conflicts).  However, in future
+    versions of Bison we plan to improve the %expect machinery so that
+    these violations will become errors again.
+
+  - Within Bison itself, numbers (e.g., goto numbers) are no longer
+    arbitrarily limited to 16-bit counts.
+
+  - Semicolons are now allowed before "|" in grammar rules, as POSIX requires.
+
+Changes in version 1.875, 2003-01-01:
+
+* The documentation license has been upgraded to version 1.2
+  of the GNU Free Documentation License.
+
+* syntax error processing
+
+  - In Yacc-style parsers YYLLOC_DEFAULT is now used to compute error
+    locations too.  This fixes bugs in error-location computation.
+
+  - %destructor
+    It is now possible to reclaim the memory associated to symbols
+    discarded during error recovery.  This feature is still experimental.
+
+  - %error-verbose
+    This new directive is preferred over YYERROR_VERBOSE.
+
+  - #defining yyerror to steal internal variables is discouraged.
+    It is not guaranteed to work forever.
+
+* POSIX conformance
+
+  - Semicolons are once again optional at the end of grammar rules.
+    This reverts to the behavior of Bison 1.33 and earlier, and improves
+    compatibility with Yacc.
+
+  - `parse error' -> `syntax error'
+    Bison now uniformly uses the term `syntax error'; formerly, the code
+    and manual sometimes used the term `parse error' instead.  POSIX
+    requires `syntax error' in diagnostics, and it was thought better to
+    be consistent.
+
+  - The documentation now emphasizes that yylex and yyerror must be
+    declared before use.  C99 requires this.
+
+  - Bison now parses C99 lexical constructs like UCNs and
+    backslash-newline within C escape sequences, as POSIX 1003.1-2001 requires.
+
+  - File names are properly escaped in C output.  E.g., foo\bar.y is
+    output as "foo\\bar.y".
+
+  - Yacc command and library now available
+    The Bison distribution now installs a `yacc' command, as POSIX requires.
+    Also, Bison now installs a small library liby.a containing
+    implementations of Yacc-compatible yyerror and main functions.
+    This library is normally not useful, but POSIX requires it.
+
+  - Type clashes now generate warnings, not errors.
+
+  - If the user does not define YYSTYPE as a macro, Bison now declares it
+    using typedef instead of defining it as a macro.
+    For consistency, YYLTYPE is also declared instead of defined.
+
+* Other compatibility issues
+
+  - %union directives can now have a tag before the `{', e.g., the
+    directive `%union foo {...}' now generates the C code
+    `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
+    The default union tag is `YYSTYPE', for compatibility with Solaris 9 Yacc.
+    For consistency, YYLTYPE's struct tag is now `YYLTYPE' not `yyltype'.
+    This is for compatibility with both Yacc and Bison 1.35.
+
+  - `;' is output before the terminating `}' of an action, for
+    compatibility with Bison 1.35.
+
+  - Bison now uses a Yacc-style format for conflict reports, e.g.,
+    `conflicts: 2 shift/reduce, 1 reduce/reduce'.
+
+  - `yystype' and `yyltype' are now obsolescent macros instead of being
+    typedefs or tags; they are no longer documented and are planned to be
+    withdrawn in a future release.
+
+* GLR parser notes
+
+  - GLR and inline
+    Users of Bison have to decide how they handle the portability of the
+    C keyword `inline'.
+
+  - `parsing stack overflow...' -> `parser stack overflow'
+    GLR parsers now report `parser stack overflow' as per the Bison manual.
+
+* Bison now warns if it detects conflicting outputs to the same file,
+  e.g., it generates a warning for `bison -d -o foo.h foo.y' since
+  that command outputs both code and header to foo.h.
+
+* #line in output files
+  - --no-line works properly.
+
+* Bison can no longer be built by a K&R C compiler; it requires C89 or
+  later to be built.  This change originally took place a few versions
+  ago, but nobody noticed until we recently asked someone to try
+  building Bison with a K&R C compiler.
+
+Changes in version 1.75, 2002-10-14:
+
+* Bison should now work on 64-bit hosts.
+
+* Indonesian translation thanks to Tedi Heriyanto.
+
+* GLR parsers
+  Fix spurious parse errors.
+
+* Pure parsers
+  Some people redefine yyerror to steal yyparse' private variables.
+  Reenable this trick until an official feature replaces it.
+
+* Type Clashes
+  In agreement with POSIX and with other Yaccs, leaving a default
+  action is valid when $$ is untyped, and $1 typed:
+
+	untyped: ... typed;
+
+  but the converse remains an error:
+
+	typed: ... untyped;
+
+* Values of mid-rule actions
+  The following code:
+
+	foo: { ... } { $$ = $1; } ...
+
+  was incorrectly rejected: $1 is defined in the second mid-rule
+  action, and is equal to the $$ of the first mid-rule action.

+be split into two packages:
+
+   bison-runtime
+        Contents: Runtime libraries and programs.
+        Audience: Anyone who wants to run internationalized programs
+                  that contain Bison-generated parsers.
+
+   bison
+        Contents: Tools and documentation for developers that use Bison.
+        Audience: Anyone who wants to develop programs that use parsers.
+        Dependencies: requires bison-runtime.
+
+The 'bison-runtime' binary package is much smaller than the 'bison'
+binary package.  It should be included in any distribution that
+contains localized programs that use the diagnostics contained in
+Bison-generated parsers.
+
+If you want to install both packages at the same time, you simply do
+at the toplevel directory:
+
+      ./configure
+      make
+      make install
+
+After installation, the file
+
+      $prefix/share/locale/*/LC_MESSAGES/bison-runtime.mo
+
+belongs to the bison-runtime package; all other installed files belong
+to the bison package.

+There are couple of available extensions of Bison targeting some XML
+output.  Some day we should consider including them.  One issue is
+that they seem to be quite orthogonal to the parsing technique, and
+seem to depend mostly on the possibility to have some code triggered
+for each reduction.  As a matter of fact, such hooks could also be
+used to generate the yydebug traces.  Some generic scheme probably
+exists in there.

+-*- outline -*-
+
+This directory contains Bison skeletons: the general shapes of the
+different parser kinds, that are specialized for specific grammars by
+the bison program.
+
+Currently, there are only three supported skeletons:
+
+- yacc.c
+  It used to be named bison.simple: it corresponds to C Yacc
+  compatible LALR(1) parsers.
+
+- lalr1.cc
+  Produces a C++ parser class.  It is still very experimental, and not
+  yet supported.  Please, subscribe to [email protected].
+
+- glr.c
+  A Generalized LR C parser based on Bison's LALR(1) tables.
+
+These skeletons are the only ones supported by the Bison team.
+Because the interface between skeletons and the bison program is not
+finished, *we are not bound to it*.  In particular, Bison is not
+mature enough for us to consider that ``foreign skeletons'' are
+supported.

+# This skeleton produces a C++ class that encapsulates a C glr parser.
+# This is in order to reduce the maintenance burden.  The glr.c
+# skeleton is clean and pure enough so that there are no real
+# problems.  The C++ interface is the same as that of lalr1.cc.  In
+# fact, glr.c can replace yacc.c without the user noticing any
+# difference, and similarly for glr.cc replacing lalr1.cc.
+#
+# The passing of parse-params
+#
+#   The additional arguments are stored as members of the parser
+#   object, yyparser.  The C routines need to carry yyparser
+#   throughout the C parser; that easy: just let yyparser become an
+#   additional parse-param.  But because the C++ skeleton needs to
+#   know the "real" original parse-param, we save them
+#   (b4_parse_param_orig).  Note that b4_parse_param is overquoted
+#   (and c.m4 strips one level of quotes).  This is a PITA, and
+#   explains why there are so many levels of quotes.
+#
+# The locations
+#
+#   We use location.cc just like lalr1.cc, but because glr.c stores
+#   the locations in a (C++) union, the position and location classes
+#   must not have a constructor.  Therefore, contrary to lalr1.cc, we
+#   must not define "b4_location_constructors".  As a consequence the
+#   user must initialize the first positions (in particular the
+#   filename member).

+	=======================
+
+	The DJGPP port of Bison offers LFN and SFN support depending on which
+	OS it is running. If LFN support is available or not is determinated at
+	run time.  If LFN support is available (DOS session under Win9X, Win2K,
+	WinXP, etc.) the standard posix file name extensions will be used.
+	These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc.  If only SFN
+	support is available (plain DOS), then the standard MSDOS short file
+	names will be used. These are: y_tab.c, y_tab.h, y.out, etc.
+	It should be noticed that this bison version needs the m4 program as
+	back end to generate the parser file (y.tab.c etc.) from the skeleton
+	files.  This implies that m4 must always be installed to get bison
+	working.  m4 will use a couple of m4 scripts that will be installed in
+	/dev/env/DJDIR/share/bison and shall not be removed.
+	It should also be noticed that the skeleton files bison.simple and
+	bison.hairy are no longer supported.  This applies also to the environ-
+	ment variables BISON_HAIRY and BISON_SIMPLE.  Those variables are *no*
+	longer honored at all.
+	The kind of skeleton file bison.hairy is no longer supported at all.
+	The skeleton file bison.simple is now called yacc.c and is an m4 script.
+	The other two skeleton files supported by this bison version are glr.c
+	and lalr1.cc.  The first one is a generalized LR C parser based on
+	Bison's LALR(1) tables and the second one is a experimental C++ parser
+	class.
+	As has been told before, bison uses m4 to generate the parser file.
+	This is done by forking and using pipes for the IPC.  MSDOS does not
+	support this functionality so this has been reproduced in the usual
+	way by redirecting stdin and stdout of bison and m4 to temporary files
+	and processing these files in sequence.  All the changes to the sources
+	are documented in the djgpp/diffs file.
+
+	Please **read** the docs.
+
+
+2.:     Installing the binary package.
+	==============================
+
+2.1.:   Copy the binary distribution into the top DJGPP installation directory,
+	just unzip it preserving the directory structure running *ONE* of the
+	following commands:
+	  unzip32 bsn@[email protected]      or
+	  djtarx bsn@[email protected]       or
+	  pkunzip -d bsn@[email protected]
+
+
+
+3.:     Building the binaries from sources.
+	===================================
+
+3.1.:   Create a temporary directory and copy the source package into the
+	directory.  If you download the source distribution from one of the
+	DJGPP sites, just unzip it preserving the directory structure
+	running *ONE* of the following commands:
+	  unzip32 bsn@[email protected]      or
+	  djtarx bsn@[email protected]       or
+	  pkunzip -d bsn@[email protected]
+	and proceed to the paragraph 3.3, below.
+
+3.2.:   Source distributions downloaded from one of the GNU FTP sites need
+	some more work to unpack, if LFN support is not available.  If LFN is
+	available then you can extract the source files from the archive with
+	any unzip program and proceed to the paragraph 3.3, below.  Any file
+	name issue will be handled by the the DJGPP configuration files.
+	To unpack the source distribution on SFN systems, first, you MUST use
+	the `djunpack' batch file to unzip the package.  That is because some
+	file names in the official distributions need to be changed to avoid
+	problems on the various platforms supported by DJGPP.
+	`djunpack' invokes the `djtar' program (that is part of the basic DJGPP
+	development kit) to rename these files on the fly given a file with
+	name mappings; the distribution includes a file `djgpp/fnchange.lst'
+	with the necessary mappings.  So you need first to retrieve that batch
+	file, and then invoke it to unpack the distribution.  Here's how:
+
+	  djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@[email protected] > djunpack.bat
+	  djunpack bison-@[email protected]
+
+	(The name of the distribution archive and the leading directory of the
+	path to `djunpack.bat' in the distribution will be different for
+	versions of Bison other than @VERSION@.)
+
+	If the argument to `djunpack.bat' include leading directories, it MUST
+	be given with the DOS-style backslashes; Unix-style forward slashes
+	will NOT work.
+
+	If the distribution comes as a .tar.bz2 archive, and your version of
+	`djtar' doesn't support bzip2 decompression, you need to unpack it as
+	follows:
+
+	  bnzip2 bison-@[email protected]
+	  djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@[email protected] > djunpack.bat
+	  djunpack bison-@[email protected]
+
+3.3.:   To build the binaries you will need the following binary packages:
+	  djdev203.zip (or a later but NOT a prior version)
+	  bsh204b.zip  (or a later but NOT a prior version)
+	  gcc410b.zip, gpp410b.zip, bnu2161b.zip, mak3791b.zip,
+	  fil40b.zip, shl20jb.zip, txt20b.zip,
+	  txi48b.zip, grep24b.zip, sed415b.zip,
+	  m4-144b.zip.
+
+	If you want to run the check you will need also:
+	  dif287b.zip
+
+	All this packages can be found in the v2gnu directory of any
+	ftp.delorie.com mirror.
+	You will need bsh204b.zip or later and *NOT* a prior version or
+	the build will fail.  The same applies to djdev203.zip.  Please note
+	that Bison requires m4-144b.zip or later to work properly.  All the
+	other packages are the ones I have used to build the binaries
+	from this source.  Previuos versions of this packages may do the
+	job as well but I have not tested this.
+
+3.4.:   If for some reason you want to reconfigure the package cd into the top
+	srcdir (bison-@TREE_VERSION@) and run the following commands:
+	  del djgpp\config.cache
+	  make clean
+	  djgpp\config
+
+	Please note that you *MUST* delete the config.cache file in the djgpp
+	subdir or you will not really reconfigure the sources because the
+	configuration informations will be read from the cache file instead
+	of being newly computed.
+	To build the programs in a directory other than where the sources are,
+	you must add the parameter that specifies the source directory,
+	e.g:
+	  x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
+
+	Lets assume you want to build the binaries in a directory placed on a
+	different drive (z:\build in this case) from where the sources are,
+	then you will run the following commands:
+	  z:
+	  md \build
+	  cd \build
+	  x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
+
+	The order of the options and the srcdir option does not matter.  You
+	*MUST* use forward slashes to specify the source directory.
+
+	The batch file will set same environment variables, make MSDOS specific
+	modifications to the Makefile.in's and supply all other needed options
+	to the configure script.
+
+3.5.:   To compile the package run from the top srcdir the command:
+	  make
+
+3.6.:   Now you can run the tests if you like.  From the top srcdir run the
+	command:
+	  make check
+
+	No test should fail but the tests #131 (Doxygen Public Documentation)
+	and #132 (Doxygen Private Documentation) will be skipped.  Please note
+	that the testsuite only works with LFN available.  On plain DOS, most
+	of the tests will fail due to invalid DOS names.
+
+3.7.:   To install the binaries, header, library, catalogs, and info docs
+	run the following command from the top srcdir:
+	  make install
+
+	This will install the products into your DJGPP installation tree given
+	by the default prefix "/dev/env/DJDIR".  If you prefer to install them
+	into some other directory you will have to set prefix to the appropiate
+	value:
+	  make install prefix=z:/some/other/place
+
+
+
+	Send GNU bison specific bug reports to <[email protected]>.
+	Send suggestions and bug reports concerning the DJGPP port to
+	comp.os.msdos.djgpp or <[email protected]>.
+
+
+Enjoy.

-Frequently Asked Questions about Bison:
-
-----------------------------------------------------------------------
-
-Q1.  Is Bison Y2K compliant?
-
-A1.  If you're looking for a guarantee or certification, I can't
-     provide it.  With a little thought you can answer this one for
-     yourself, though.  (Hint: does a parser generator rely on the
-     date or time for anything?)  If you're still confused, see
-     http://www.gnu.org/software/year2000.html for more information.
-
-----------------------------------------------------------------------
-
-Q2.  I can't build Bison because "make" complains that "msgfmt" is not
-     fund.  What should I do?
-
-A2.  Like most GNU packages with internationalization support, that
-     feature is turned on by default.  If you have problems building
-     in the "po" subdirectory, it indicates that your system's
-     internationalization support is lacking.  You can re-configure
-     Bison with "--disable-nls" to turn off this support, or you can
-     install GNU gettext from ftp://ftp.gnu.org/gnu/gettext/ and
-     re-configure Bison.  See the file "ABOUT-NLS" for more
-     information.
-
-----------------------------------------------------------------------
-
-Q3.  I'm having trouble using Bison.  Where can I find help?
-
-A3.  First, read the fine manual which comes with bison.  Beyond that,
-     you can send mail to <[email protected]>.  This mailing list is
-     intended to be populated with people who are willing to answer
-     questions about using and installing Bison.  Please keep in mind
-     that (most of) the people on the list have aspects of their lives
-     which are not related to Bison (!), so you may not receive an
-     answer to your question right away.  This can be frustrating, but
-     please try not to honk them off; remember that any help they
-     provide is purely voluntary and out of the kindness of their
-     hearts.
-
-----------------------------------------------------------------------
-
-Q4.  I found a bug.  What should I include in the bug report?
-
-A4.  Before you send a bug report, make sure you are using the latest
-     version.  Check ftp://ftp.gnu.org/pub/gnu/bison/ or one of its
-     mirrors.  Be sure to include the version number in your bug
-     report.  If the bug is present in the latest version but not in a
-     previous version, try to determine the most recent version which
-     did not contain the bug.
-
-     If the bug is parser-related, you should include the smallest
-     grammar you can which demonstrates the bug.  The grammar file
-     should also be complete (i.e., I should be able to run it through
-     Bison without having to edit or add anything).  The smaller and
-     simpler the grammar, the easier it will be to fix the bug.
-
-     Include information about your compilation environment, including
-     your operating system's name and version and your compiler's name
-     and version.  If you have trouble compiling, you should also
-     include a transcript of the build session, starting with the
-     invocation of `configure'.  Depending on the nature of the bug,
-     you may be asked to send additional files as well (such as
-     `config.h' or `config.cache').
-
-     Patches are most welcome, but not required.  That is, do not
-     hesitate to send a bug report just because you can not provide a
-     fix.
-
-     Send bug reports to <[email protected]>.
-
-----------------------------------------------------------------------
-
-Q5.  Will Bison ever have C++ support?
-
-A5.  Yes, it's in the works.  Things are very chaotic right now, but
-     what little information floats around is posted to the bug-bison
-     mailing list.  If you're interested in testing C++ support when
-     it becomes available, please consider subscribing to the list,
-     especially if you are willing to beta test other releases as
-     well.
-
-----------------------------------------------------------------------
-
-Q6.  What is involved in being a beta tester?
-
-A6.  It's not terribly involved.  Basically, you would download a test
-     release, compile it, and use it to build and run a parser or two.
-     After that, you would submit either a bug report or a message
-     saying that everything is okay.  It is important to report
-     successes as well as failures because test releases eventually
-     become mainstream releases, but only if they are adequately
-     tested.  If no one tests, development is essentially halted.
-
-     Beta testers are particularly needed for operating systems to
-     which I do not have access.  I currently have easy access to
-     Linux (x86 glibc 2.1), Solaris (SPARC) 2.6 and 2.7, and HP-UX
-     10.20.  Reports about other operating systems are especially
-     welcome.
-
-----------------------------------------------------------------------
-
-Q7.  How do I join the help-bison and bug-bison mailing lists?
-
-A7.  See http://www.gnu.org/ (the section about "GNU mailing lists")
-     for more information.

-2 Parameters
-.skip
- file-spec
-.skip
-Here file-spec is the grammar file name, which usually ends in
-.y.  The parser file's name is made by replacing the .y
-with _tab.c.  Thus, the command bison foo.y yields
-foo_tab.c.
-
-.skip
-.indent -1
-2 Qualifiers
-.skip
- The following is the list of available qualifiers for BISON:
-.literal
-	/DEBUG
-	/DEFINES
-	/FILE_PREFIX=prefix
-	/FIXED_OUTFILES
-	/NAME_PREFIX=prefix
-	/NOLINES
-	/NOPARSER
-	/OUTPUT=outfilefile
-	/RAW
-	/TOKEN_TABLE
-	/VERBOSE
-	/VERSION
-	/YACC
-.end literal
-.skip
-.indent -1
-2 /DEBUG
-.skip
-In the parser file,
-define the macro YYDEBUG to 1 if it is not already defined,
-so that the debugging facilities are compiled.
-.skip
-.indent -1
-2 /DEFINES
-.skip
-Write an extra output file containing macro definitions for the token
-type names defined in the grammar and the semantic value type
-YYSTYPE, as well as a extern variable declarations.
-.skip
-If the parser output file is named "name.c" then this file
-is named "name.h".
-.skip
-This output file is essential if you wish to put the definition of
-yylex in a separate source file, because yylex needs to
-be able to refer to token type codes and the variable
-yylval.
-.skip
-.indent -1
-2 /FILE_PREFIX
-.skip
-.literal
-  /FILIE_PREFIX=prefix
-.end literal
-.skip
-	Specify a prefix to use for all Bison output file names.  The names are
-chosen as if the input file were named prefix.c
-
-.skip
-.indent -1
-2 /FIXED_OUTFILES
-.skip
-Equivalent to /OUTPUT=y_tab.c; the parser output file is called
-y_tab.c, and the other outputs are called y.output and
-y_tab.h.  The purpose of this switch is to imitate Yacc's output
-file name conventions.  The /YACC qualifier is functionally equivalent
-to /FIXED_OUTFILES.  The following command definition will
-work as a substitute for Yacc:
-
-.literal
-$YACC:==BISON/FIXED_OUTFILES
-.end literal
-.skip
-.indent -1
-2 /NAME_PREFIX
-.skip
-.literal
-  /NAME_PREFIX=prefix
-.end literal
-.skip
-Rename the external symbols used in the parser so that they start with
-"prefix" instead of "yy".  The precise list of symbols renamed
-is yyparse, yylex, yyerror, yylval, yychar and yydebug.
-
-For example, if you use /NAME_PREFIX="c", the names become cparse,
-clex, and so on.
-
-.skip
-.indent -1
-2 /NOLINES
-.skip
-Don't put any "#line" preprocessor commands in the parser file.
-Ordinarily Bison puts them in the parser file so that the C compiler
-and debuggers will associate errors with your source file, the
-grammar file.  This option causes them to associate errors with the
-parser file, treating it an independent source file in its own right.
-.skip
-.indent -1
-2 /NOPARSER
-.skip
-Do not generate the parser code into the output;  generate only
-declarations.  The generated name_tab.c file will have only 
-constant declarations.  In addition, a name.act file is
-generated containing a switch statement body containing all the
-translated actions. 
-.skip
-.indent -1
-2 /OUTPUT
-.skip
-.literal
-  /OUTPUT=outfile
-.end literal
-.skip
-Specify the name "outfile" for the parser file.
-.skip
-.indent -1
-2 /RAW
-.skip
-When this switch is specified, the .tab.h file defines the tokens to
-have the bison token numbers rather than the yacc compatible numbers.
-To employ this switch you would have to have your own parser.
-.skip
-.indent -1
-2 /TOKEN_TABLE
-.skip
-This switch causes the name_tab.c output to include a list of 
-token names in order by their token numbers;  this is defined in the array 
-yytname.  Also generated are #defines for YYNTOKENS, YYNNTS, YYNRULES,
-and YYNSTATES.
-
-.skip
-.indent -1
-2 /VERBOSE
-.skip
-Write an extra output file containing verbose descriptions of the
-parser states and what is done for each type of look-ahead token in
-that state.
-.skip
-This file also describes all the conflicts, both those resolved by
-operator precedence and the unresolved ones.
-.skip
-The file's name is made by removing _tab.c or .c from
-the parser output file name, and adding .output instead.
-.skip
-Therefore, if the input file is foo.y, then the parser file is
-called foo_tab.c by default.  As a consequence, the verbose
-output file is called foo.output.
-.skip
-.indent -1
-2 /VERSION
-.skip
-Print the version number of Bison.
-

+(including scanning and I/O).
+
+Set the envvars BISON and CC to the programs and flags you want to
+use.  They default to bison and gcc.  To run a non-installed bison
+from a tarball built in _build, I suggest the following.
+
+     BISON=_build/tests/bison CC='gcc -O2' ./bench.pl
+
+(The _build/tests/bison wrapper makes sure that _build/src/bison will
+use the tarballs' skeletons, not those already installed as a
+straightforward use of _build/src/bison would.)

-# This scripts eases checking in changes to CVS-maintained projects
-# with ChangeLog files.  It will check that there have been no
-# conflicting commits in the CVS repository and print which files it
-# is going to commit to stderr.  A list of files to compare and to
-# check in can be given in the command line.  If it is not given, all
-# files in the current directory (and below, unless `-l' is given) are
-# considered for check in.
-
-# The commit message will be extracted from the differences between a
-# file named ChangeLog* in the commit list, or named after -C, and the
-# one in the repository (unless a message was specified with `-m' or
-# `-F').  An empty message is not accepted (but a blank line is).  If
-# the message is acceptable, it will be presented for verification
-# (and possible edition) using the $PAGER environment variable (or
-# `more', if it is not set, or `cat', if the `-f' switch is given).
-# If $PAGER exits successfully, the modified files (at that moment)
-# are checked in, unless `-n' was specified, in which case nothing is
-# checked in.

-/* alloca.c -- allocate automatically reclaimed memory
-   (Mostly) portable public-domain implementation -- D A Gwyn
-
-   This implementation of the PWB library alloca function,
-   which is used to allocate space off the run-time stack so
-   that it is automatically reclaimed upon procedure exit,
-   was inspired by discussions with J. Q. Johnson of Cornell.
-   J.Otto Tennant <[email protected]> contributed the Cray support.
-
-   There are some preprocessor constants that can
-   be defined when compiling for your specific system, for
-   improved efficiency; however, the defaults should be okay.
-
-   The general concept of this implementation is to keep
-   track of all alloca-allocated blocks, and reclaim any
-   that are found to be deeper in the stack than the current
-   invocation.  This heuristic does not reclaim storage as
-   soon as it becomes invalid, but it will do so eventually.
-
-   As a special case, alloca(0) reclaims storage without
-   allocating any.  It is a good idea to use alloca(0) in
-   your main control loop, etc. to force garbage collection.  */
