* NEWS: Version 2.0b.

* 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.
* src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
* src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
* src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
* tests/sets.at: 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.
* src/reader.h (gram_end, gram_lineno): New decls to pacify
"make maintainer-distcheck".
* src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
(skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
(skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
(skel_lex_destroy, scan_skel): Move these decls to...
* 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.
