* src/gram.c (dummy): Remove, now there is actual code in gram.c.
(This useless function was defined only to work around VMS linkers
that can't handle compilation units with variables only).
* src/reduce.c (dump_grammar): Use it to trace the construction of
ritem.
* tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
now the tests are run in private dirs, therefore AC_CLEANUP and
family can be simplified to 0-ary.
* tests/atlocal.in: Now that we run `elsewhere' than in tests/,
use abs. path to find config.h.
able to understand that `--out' is OK: the two racing long options
are aliases.
(usage): Adjust.
* src/lex.h (tok_setopt): Remove, replaced with...
(tok_intopt, tok_stropt): these new guys.
* src/lex.c (getopt.h): Not needed.
(token_buffer, unlexed_token_buffer): Not const.
(percent_table): Promote `-' over `_' in directive names.
Active `%name-prefix', `file-prefix', and `output'.
(parse_percent_token): Accept possible arguments to directives.
Promote `-' over `_' in directive names.
* doc/bison.texinfo (Decl Summary): Split the list into
`directives for grammars' and `directives for bison'.
Sort'em.
Add description of `%name-prefix', `file-prefix', and `output'.
Promote `-' over `_' in directive names.
(Bison Options): s/%locactions/%locations/. Nice Freudian slip.
Simplify the description of `--name-prefix'.
Promote `-' over `_' in directive names.
Promote `--output' over `--output-file'.
Fix the description of `--defines'.
* tests/output.at: Exercise %file-prefix and %output.
* lib/quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct
tm to be declared.
(HAVE_MBSINIT): Undef if !HAVE_MBRTOWC.
(mbsinit): Define to 1 if !defined mbsinit && !HAVE_MBSINIT.
* m4/Makefile.am (EXTRA_DIST): Add mbrtowc.m4.
* m4/mbrtowc.m4: New file.
* m4/prereq.m4 (jm_PREREQ_QUOTEARG): Check for mbsinit and stddef.h.
Use jm_FUNC_MBRTOWC instead of AC_CHECK_FUNCS(mbrtowc).
