files include <stdio.h> before <config.h>, which messes up because the latter defines __EXTENSIONS__. Address the problem by creating two new little files that include <config.h> first, then include the flex-generated files. Rewrite everyone else to include <config.h> first, as well. * lib/timevar.c: Always include "config.h". * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with scan-gram-c.c, and scan-skel.l with scan-skel-c.c. (EXTRA_bison_SOURCES): New macro. * src/scan-gram-c.c, src/scan-skel-c.c: New files. * src/system.h: Don't include config.h. * src/LR0.c: Include <config.h> first. * src/assoc.c: Likewise. * src/closure.c: Likewise. * src/complain.c: Likewise. * src/conflicts.c: Likewise. * src/derives.c: Likewise. * src/files.c: Likewise. * src/getargs.c: Likewise. * src/gram.c: Likewise. * src/lalr.c: Likewise. * src/location.c: Likewise. * src/main.c: Likewise. * src/muscle_tab.c: Likewise. * src/nullable.c: Likewise. * src/output.c: Likewise. * src/parse-gram.y: Likewise. * src/print.c: Likewise. * src/print_graph.c: Likewise. * src/reader.c: Likewise. * src/reduce.c: Likewise. * src/relation.c: Likewise. * src/state.c: Likewise. * src/symlist.c: Likewise. * src/symtab.c: Likewise. * src/tables.c: Likewise. * src/uniqstr.c: Likewise. * src/vcg.c: Likewise.
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.
