+
+	Version 1.875b.
+
+	* NEWS: Document 1.875b.
+
+	* lib/bbitset.h: Do not include config.h; that's the includer's job.
+	Do not include <sys/types.h>; shouldn't be needed on a C89 host.
+	* lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
+	Don't use 'index' in comments, as it's a builtin fn on some hosts.
+	* lib/bitset_stats.c: Include gettext.h unconditionally, as
+	per recent gettext manual's suggestion.
+	* lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
+	Use prototypes, not old-style definitions.
+	* lib/lbitset.c (lbitset_unused_clear): Likewise.
+	* lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
+	vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
+	vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
+	vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
+	vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
+	vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
+	vbitset_or_and_cmp, vbitset_copy): Likewise.
+
+	* lib/libiberty.h: Do not include config.h; that's the includer's job.
+	Do not include <stdlib.h>.
+	(PARAMS): Define unconditionally for C89.
+	(ATTRIBUTE_NORETURN): Remove.
+	(ATTRIBUTE_UNUSED): Define unconditionally.
+
+	Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
+	<http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
+	* lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
+	* lib/vbitset.c, lib/vbitset.h: New files.
+	* lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
+	lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
+	from libbitset.
+
+	* doc/bison.texinfo (How Can I Reset the Parser): Renamed from
+	`How Can I Reset @code{yyparse}', since texinfo does not allow
+	arbitrary @ in node names.
+
+	* m4/Makefile.am (EXTRA_DIST): Add the following files, which
+	shouldn't be needed according to the gettext 0.12.1 documentation
+	but which seem to be needed anyway: codeset.m4 glibc21.m4
+	intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4
+	lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
+
+	* lib/.cvsignore: Add stdbool.h.
+	* m4/.cvsignore: Add nls.m4, po.m4.
+
+	Upgrade to CVS gnulib.
+	* stdbool_.h: File renamed from stdbool.h.in.
+	* configure.ac (AM_STDBOOL_H): Invoke this instead of
+	AC_HEADER_STDBOOL.
+	(AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
+	(AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
+	* lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
+	(MOSTLYCLEANFILES): New var.
+	($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
+	(stdbool.h): New rule.
+	* lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
+	lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
+	lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
+	m4/quote.m4: Upgrade to today's gnulib.
+
+	* tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
+	(AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
+	the tests right now.
+	* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
+	yyerror are declared before use; C99 requires this.
