<http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>. * src/parse-gram.y (symbol_declaration): Don't put statements before declarations; it's not portable to C89. * src/scan-code.l (handle_action_at): Likewise. * src/scan-code.l: Always initialize braces_level; the old code left it uninitialized and therefore had undefined behavior. Don't attempt to redefine 'assert', since it runs afoul of systems where standard headers (mistakenly) include <assert.h>. Instead, define and use our own alternative, called 'aver'. * src/reader.c: Don't include assert.h, since we no longer use assert. * src/scan-code.l: Likewise. * src/system.h (assert): Remove, replacing with.... (aver): New function, taking a bool arg. All uses changed. * src/tables.c (pack_vector): Ensure that aver arg is bool, not merely an integer.
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.
