Akim Demaille
be2a1a68ef Give a try to M4 as a back end. 
* lib/readpipe.c: New, from wdiff.
* src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
BISON_HAIRY.
* src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
specific values.  Now it is m4 that performs the lookup.
* src/parse-skel.y: Remove.
* src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
* src/output.c (actions_output, guards_output)
(token_definitions_output): No longer keeps track of the output
line number, hence remove the second argument.
(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'.
* data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
shamelessly stolen from CVS Autoconf.

2992e1e967 (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).

82841af7d0 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.
