Bison News
----------
+Changes in version 1.49a:
+\f
+Changes in version 1.30:
+
+* `--defines' and `--graph' have now an optionnal argument which is the
+ output file name. `-d' and `-g' do not change, they do not take any
+ argument.
+
+* `%source_extension' and `%header_extension' are removed, failed
+ experiment.
+
+* Portability fixes.
+\f
+Changes in version 1.29, 2001-09-07:
+
+* The output file does not define const, as this caused problems when used
+ with common autoconfiguration schemes. If you still use ancient compilers
+ that lack const, compile with the equivalent of the C compiler option
+ `-Dconst='. autoconf's AC_C_CONST macro provides one way to do this.
+
+* Added `-g' and `--graph'.
+
+* The Bison manual is now distributed under the terms of the GNU FDL.
+
+* The input and the output files has automatically a similar extension.
+
+* Russian translation added.
+
+* NLS support updated; should hopefully be less troublesome.
+
+* Added the old Bison reference card.
+
+* Added `--locations' and `%locations'.
+
+* Added `-S' and `--skeleton'.
+
+* `%raw', `-r', `--raw' is disabled.
+
+* Special characters are escaped when output. This solves the problems
+ of the #line lines with path names including backslashes.
+
+* New directives.
+ `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose',
+ `%debug', `%source_extension' and `%header_extension'.
+
+* @$
+ Automatic location tracking.
+\f
+Changes in version 1.28, 1999-07-06:
+
+* Should compile better now with K&R compilers.
+
+* Added NLS.
+
+* Fixed a problem with escaping the double quote character.
+
+* There is now a FAQ.
+\f
+Changes in version 1.27:
+
+* The make rule which prevented bison.simple from being created on
+ some systems has been fixed.
+\f
+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().
+\f
+Changes in version 1.25, 1995-10-16:
+
+* 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.
+\f

The user can define YYPARSE_PARAM as the name of an argument to be

-
Line numbers in output file corrected.
-
-Configuration and compilation problems fixed.
\f
Changes in version 1.22:
