Update the `configure' tool chain. * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by src/makefile.am. (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED. (AC_OUTPUT): Add m4/Makefile. Bump to bison 1.28a, 1.29 has never been released. * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are handled via src/Makefile.am. (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS, HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by autoheader. * Makefile.am (SUBDIRS): Add m4. (ACLOCAL_AM_FLAGS): New variable. (AUTOMAKE_OPTIONS): Add check-news. * src/Makefile.am (bison.simple): Use awk to replace #line lines with the proper line number and file name. (DEFS): Propagate the location of bison library files and of the locale files. (INCLUDES): Added `-I ..' so that one can compile with srcdir != builddir. * acinclude.m4: Remove, replaced by the directory m4. * m4/Makefile.am (EXTRA_DIST): New variable. * m4/gettext.m4: New file, from the fileutils. * m4/lcmessage.m4: Likewise * m4/progtest.m4: Likewise. * m4/bison-decl.m4: New file, extracted from former acinclude.m4.

||
----------
|
||
|
||
Changes in version 1.28a:
|
||
|
||
* Russian translation added.
|
||
|
||
* NLS support updated; should hopefully be less troublesome.
|
||
|
||
* Added the old Bison reference card.
|
||
|
||
Changes in version 1.28:
|
||
|
||
* Should compile better now with K&R compilers.
|
||
|
||
* Added NLS.
|
||
|
||
* Fixed a problem with escaping the double quote character.
|
||
|
||
* There is now a FAQ.
|
||
|
||
Changes in version 1.27:
|
||
|
||
* The make rule which prevented bison.simple from being created on
|
||
some systems has been fixed.
|
||
|
||
Changes in version 1.26:
|
||
|
||
* Bison now uses automake.
|
||
|
||
* New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>.
|
||
|
||
* Token numbers now start at 257 as previously documented, not 258.
|
||
|
||
* Bison honors the TMPDIR environment variable.
|
||
|
||
* A couple of buffer overruns have been fixed.
|
||
|
||
* Problems when closing files should now be reported.
|
||
|
||
* Generated parsers should now work even on operating systems which do
|
||
not provide alloca().
|
||
|
||
Changes in version 1.25:
|
||
|
||
* Errors in the input grammar are not fatal; Bison keeps reading
|
||
the grammar file, and reports all the errors found in it.
|
||
|
||
* Tokens can now be specified as multiple-character strings: for
|
||
example, you could use "<=" for a token which looks like <=, instead
|
||
of chosing a name like LESSEQ.
|
||
|
||
* The %token_table declaration says to write a table of tokens (names
|
||
and numbers) into the parser file. The yylex function can use this
|
||
table to recognize multiple-character string tokens, or for other
|
||
purposes.
|
||
|
||
* The %no_lines declaration says not to generate any #line preprocessor
|
||
directives in the parser file.
|
||
|
||
* The %raw declaration says to use internal Bison token numbers, not
|
||
Yacc-compatible token numbers, when token names are defined as macros.
|
||
|
||
* The --no-parser option produces the parser tables without including
|
||
the parser engine; a project can now use its own parser engine.
|
||
The actions go into a separate file called NAME.act, in the form of
|
||
a switch statement body.
|
||
|
||
Changes in version 1.23:
|
||
|
||
The user can define YYPARSE_PARAM as the name of an argument to be
|
||
passed into yyparse. The argument should have type void *. It should
|
||
actually point to an object. Grammar actions can access the variable
|
||
by casting it to the proper pointer type.
|
||
|
||
Line numbers in output file corrected.
|
||
|
||
Changes in version 1.22:
|
||
|
||
--help option added.
|
||
|
||
Changes in version 1.20:
|
||
|
||
Output file does not redefine const for C++.
