#define statements unless `--yacc' is specified; always use enum yytokentype. Most important discussions start at: <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>, <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>, and <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>. * NEWS (2.3+): Mention. * data/c.m4 (b4_yacc_if): New. (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the token #define's. * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc' on token name definitions. * src/getargs.c (usage): Capitalize `Yacc' in English. * src/output.c (prepare): Define b4_yacc_flag. * tests/regression.at (Early token definitions): Test that tokens names are defined before the pre-prologue not just before the post-prologue. Remove this test case and copy to... (Early token definitions with --yacc): ... this to test #define's. (Early token definitions without --yacc): ... and this to test enums.
This directory contains the Bison parser generator. See the file INSTALL for generic compilation and installation instructions. See the file doc/FAQ for frequently asked questions. Bison requires GNU m4 1.4.3 or later. See: ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz Bison can work with pre-1.4.3 distributions of GNU m4 if they are sufficiently patched, but if you encounter a bug with an older distribution and report a bug we will probably suggest that you upgrade to 1.4.3 as the first step in trying to fix it. Please send bug reports to <bug-bison@gnu.org>. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report. If you have questions about using Bison and the documentation does not answer them, please send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004, 2005 Free Software Foundation, Inc.
