+
+ Remove the support for C++ namespace cleanliness; it was

+ (guards_output): Check against the guard member of a rule, not the
+ action member.
+ Adjust callers.
+ (output_skeleton): Don't look for the skeleton location, let m4 do
+ that.
+ Create `/tmp/muscles.m4'. This is temporary, a proper temporary
+ file will be used.
+ Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
+ (prepare): Given that for the time being changesyntax is not
+ usable in M4, rename the muscles using `-' to `_'.
+ Define `defines_flag', `output_parser_name' and `output_header_name'.
+ * src/output.h (actions_output, guards_output)
+ (token_definitions_output): Adjust prototypes.
+ * src/scan-skel.l: Instead of scanning the skeletons, it now
+ processes the output of m4: `__oline__' and `#output'.
+ * data/bison.simple: Adjust to be used by M4(sugar).
+ * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
+ to date.
+ * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
+ instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.

+2002-01-29 Paul Eggert <eggert@twinsun.com>

+ * src/bison.simple (YYSIZE_T): Do not define merely because
+ YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
+ On some platforms, <alloca.h> does not declare YYSTD (size_t).
+
+2002-01-27 Akim Demaille <akim@epita.fr>
+
+ Fix `%nonassoc and eof'.
+
+ * src/state.c (errs_dup): Aaaah! The failure was due to bytes
+ which were not properly copied! Replace
+ memcpy (res->errs, src->errs, src->nerrs);
+ with
+ memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
+ !!!
+ * tests/regression.at (%nonassoc and eof): Adjust to newest
+ Autotest: `.' is not in the PATH.

- * src/system.h: Need to define __attribute__ away for non-GCC
+ * src/system.h: Need to define __attribute__ away for non-GCC
compilers as well (i.e. the vendor C compiler).
