GNU/Linux and Solaris that support unlocked I/O. The basic idea
is to use the gnlib unlocked-io module, and to prefer putc and
puts to printf when either will work (since the latter doesn't
come in an unlocked flavor).
* bootstrap (gnulib_modules): Add unlocked-io.
* data/c.m4 (yysymprint): Prefer puts and putc to printf.
* data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
Prefer them to YYFPRINTF and YYDPRINTF if either will do,
and similarly for puts and putc and printf.
* data/yacc.c: Likewise.
* lib/bitset.c (bitset_print): Likewise.
* lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
* lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
to printf.
* lib/lbitset.c (debug_lbitset): Likewise.
* src/closure.c (print_firsts, print_fderives): Likewise.
* src/gram.c (grammar_dump): Likewise.
* src/lalr.c (look_ahead_tokens_print): Likewise.
* src/output.c (escaped_output): Likewise.
(user_actions_output): Coalesce two printfs.
* src/parse-gram.h (%printer): Prefer putc and puts to printf.
* src/reduce.c (reduce_print): Likewise.
* src/state.c (state_rule_look_ahead_tokens_print): Likewise.
* src/system.h: Include unlocked-io.h rathe than stdio.h.
* data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
the user's name space. All uses changed to __attribute__
((__unused__)).
(yyFail, yyMemoryExhausted, yyreportAmbiguity):
Add __attribute__ ((__noreturn__)).
* etc/clcommit: Remove. We weren't using it, and it failed
"make maintainer-distcheck".
* Makefile.maint: Merge from coreutils.
(CVS_LIST, CVS_LIST_EXCEPT): New macros.
(syntax-check-rules): Change list of rules as described below.
(sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
(sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
(sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
(sc_trailing_space): New rules.
(sc_xalloc_h_in_src): Remove.
(sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
(sc_space_tab, sc_error_exit_success, sc_changelog):
(sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
(makefile-check, po-check, author_mark_check):
(makefile_path_separator_check, copyright-check):
Use grep -n, to make it easier to find violations.
Use CVS_LIST and CVS_LIST_EXCEPT.
(header_regexp, h_re): Remove.
(dd_c): New macro.
(sc_dd_max_sym_length, .re-list, news-date-check): New rules.
(my-distcheck): Use more-modern GCC flags.
(signatures, %.asc): Remove.
(rel-files, announcement): Remove signatures.
Restore old updating code, even though we don't use it, so
that we're the same as coreutils.
(alpha, beta, major): Depend on news-date-check.
Make the upload commands.
* data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
* lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
* lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
* lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

* data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
we comment out the Autoconf version number.
* doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
it's error-prone and "make maintainer-distcheck" rejects it.
* lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
Indent calls to "error" to pacify "make maintainer-distcheck",
when the calls are not intended to be translated.
* m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
* src/Makefile.am (DEFS): Use +=, to pacify
"make maintainer-distcheck".
(bison_SOURCES): Add scan-skel.h.
(sc_tight_scope): New rule, from coreutils.
* src/files.c (src_extension, header_extension):
Now static, not extern.
* src/getargs.c (short_options): Likewise.
* src/muscle_tab.c (muscle_table): Likewise.
* src/parse-gram.y (current_class, current_type, current_prec):
Likewise.
* src/reader.c (grammar_end, previous_rule_end): Likewise.
* src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
* src/main.c (main): Cast bindtextdomain and textdomain calls to
void, to avoid warning when NLS is disabled.
* src/output.c: Include scan-skel.h.
(scan_skel): Remove decl, since scan-skel.h does this.
(output_skeleton):
Indent calls to "error" to pacify "make maintainer-distcheck".
* src/print_graph.c: Don't include <obstack.h>, as system.h does this.

"make maintainer-distcheck".

* src/scan-skel.h: New file.
* src/uniqstr.c (uniqstr_assert):
Indent calls to "error" to pacify "make maintainer-distcheck".
* tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
not @VAR@.
* tests/torture.at: Revamp to avoid misuse of atoi that
"make maintainer-distcheck" complained about.
(union bitset_union, struct abitset_struct, struct ebitset_struct,
struct lbitset_struct, struct bitset_stats_struct): New types.
All uses of struct bitset_struct changed to union bitset_union,
etc.
(bitset_next, bitset_prev, bitset_only_set_p): Declare.
