* bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
Add fopen-safer.
(gnulib_files): Add m4/warning.m4. Don't worry about files
overwritten by autopoint.
Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
Suppress "id", "ms", "tr" translations for now, since gettext 0.15
rejects them.
Don't use autoreconf; instead, invoke autopoint etc. by hand,
so that we can remove the intl files at a better time.
(intl_files_to_remove): Remove aclocal.m4, since it gets
rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
Remove datarootdir hack; no longer needed.
* configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
(AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
* lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
strdup.h.
* m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
* m4/warning.m4: Remove from CVS, since we now use gnulib's version.
YYSTYPE if your grammar contains at least one <type> tag.
Your YYSTYPE need not be a macro; it can be a typedef.
* doc/bison.texinfo (Value Type, Multiple Types, Location Type):
(Union Decl, Decl Summary): Document this.
* data/glr.c (YYSTYPE): Implement this.
* data/glr.cc (YYSTYPE): Likewise.
* data/lalr1.cc (YYSTYPE): Likewise.
* data/yacc.c (YYSTYPE): Likewise.
* src/output.c (prepare): Output tag_seen_flag.
* src/parse-gram.y (declaration, grammar_declaration):
Use 'union_seen' rather than 'typed' to determine whether
%union has been seen, since grammars can now be typed without
%union.
(symbol_declaration, type.opt, symbol_def):
Keep track of whether a tag has been seen.
* src/reader.c (union_seen, tag_seen): New vars.
(typed): remove.
* src/reader.h (union_seen, tag_seen, typed): Likewise.
* src/scan-code.l (untyped_var_seen): New variable.
(handle_action_dollar): Adjust to above changes.
(handle_action_dollar, handle_action_at):
Improve overflow checking for outlandish numbers.
* tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
avoid new diagnostics generated by above changes.
* tests/regression.at (YYSTYPE typedef): Add test to check
for type tags without %union.
so they don't collide with user-defined macros.
(yy_stack_print): Don't assume that yytype_int16 promotes to int;
this was never guaranteed, and now that we're using gnulib stdint,
which defines int_fast16_t to long int, the problem is exposed.
* bootstrap (gnulib_modules): Add stdint.
Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
no longer copies it.
(intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
since stdint needs the former and wcwidth (which is now required
by mbswidth) needs the latter.
Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
work around a compatibility glitch between gettext 0.14.6 and
Autoconf 2.60.
* configure.ac (AC_PREREQ): Require Autoconf 2.60.
Do not check for uintptr_t, since new stdint module does the right
thing.
* lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
Add stdint.h, stdint_.h, wcwidth.h.
* m4/.cvsignore: Remove alloca.m4, onceonly.m4.
Add absolute-header.m4, double-slash-root.m4, longlong.m4,
stdint.m4, wchar_t.m4, wcwidth.m4.
* src/files.c: Include <dirname.h> and <stdio-safer.h> in the
usual order for ../lib/*.h files.
(file_name_split): Use last_component, not base_name, to adjust
to gnulib changes.
* src/parse-gram.h: Include <strverscmp.h> in the usual order
for ../lib/*.h files.
(YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
Define unconditionally, since we now assume the stdint module.
* src/scan-skel.l: Include <dirname.h>.
(BASE_QPUTS): Use last_component, not base_name.
* src/system.h: Include <unlocked-io.h> in the usual order
for ../lib/*.h files. Include <stdint.h> unconditionally,
since we now use the stdint module.
(uintptr_t): Declare if UINTPTR_MAX is not defined, not
HAVE_UINTPTR_T, since we now use the stdint module.
(base_name): Remove decl, since files now include <dirname.h>
to get the decl.
(CHAR, STRING, string_content): For %printer, properly escape.
(ID): Prefer fputs to fprintf.
(id): Reindent to be consistent with other rules.
Properly quote char.
(get_translations): New function, which uses HTML scraping to
deduce locations of latest translations.
Use this function to grab both bison and bison-runtime .po files.
Don't bother priming the pump for the runtime-po domain any more,
as it's now translated better than bison is.

compatibility with data/yacc.c. Problem reported by John P. Hartmann in

* doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
Document this.

(using GNU make) does not worry about configuring gzip. This also
works around a bug reported independently by Keith Thompson and by
Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
stderr rather than stdout, messing up the build logs.
(b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
'const YYSTYPE', and similarly for YYLTYPE. This fixes one
of the bugs reported today by Derek M Jones in
<http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
* doc/bison.texinfo (Value Type): Document that YYSTYPE must be
defined to be a type name without parens or brackets.
(Location Type): Similarly for YYLTYPE.
* tests/regression.at (Trivial grammars): Put in a test for this
bug that will be caught by 'make maintainer-check' (though not,
alas, by 'make check' unless your compiler is picky).

Modify yylex so that it uses its argument, rather than trying

when two actions appeared in succession, the second one was
scanned before the first one was added to the grammar rule
as a midrule action. Bison then output the incorrect warning
"parse.y:905.17-906.36: warning: unused value: $3".
* src/parse-gram.y (BRACED_CODE, action): These are no longer

(action): Invoke it here instead.
* src/reader.c (grammar_midrule_action): Now extern.
