+2003-01-04  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
+	since GNU C++ (as of 3.2.1) does not allow attributes on labels.
+	Problem reported by Nelson H. F. Beebe.
+
+2003-01-03  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
+	(void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
+	when compiling Bison 1.875's `bitset bset = obstack_alloc
+	(bobstack, bytes);'.  Problem reported by Nelson H. F. Beebe.
+
+	* src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
+	([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
+	grow to a huge size with typical invocation.
+	
+	* lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
+	Use the pattern recommended by Autoconf 2.57, except also protect
+	against double-definition.
+	* src/system.h: Likewise.
+	Portability issues reported by Nelson H. F. Beebe.
+	
+	* data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
+	All uses changed.  Provide a definition in both C and C++.
+	(yytrue, yyfalse): Define even if defined (__cplusplus).
+
+	* lib/bitset_stats.c (bitset_stats_list): Remove unused var.
+	Reported by Nelson H. F. Beebe.
+	
+	* src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
+
+2003-01-02  Paul Eggert  <eggert@twinsun.com>
+
+	* data/yacc.c (yyerrlab1): Append `;' after attribute, to
+	pacify the buggy "smart preprocessor" in MacOS 10.2.3.
+	Bug reported by Nelson H. F. Beebe.
+
+2003-01-01  Paul Eggert  <eggert@twinsun.com>
+
+	* Version 1.875.
+
+2002-12-30  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
+	Moved here from...
+	(<INITIAL>","): Here.  This causes stray "," to be treated
+	more uniformly.
+
+	* src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
+	last brace in braced code when not in Yacc mode, for compatibility
+	with Bison 1.35.  This resurrects the 2001-12-15 patch to
+	src/reader.c.
+
+	* src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
+	yystype.  This follows up the 2002-12-24 YYSTYPE bug fix.
+
+2002-12-28  Paul Eggert  <eggert@twinsun.com>
+
+	* src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
+	that of SYM's type.  This fixes Debian bug 168069, reported by
+	Thomas Olsson.
+	
+2002-12-28  Paul Eggert  <eggert@twinsun.com>
+
+	Version 1.75f.
+
+	Switch back to the Yacc style of conflict reports, undoing some
+	of the 2002-07-30 change.
+	* doc/bison.texinfo (Understanding): Use Yacc style for
+	conflict reports.  Also, use new way of locating rules.
+	* src/conflicts.c (conflict_report):
+	Renamed from conflict_report_yacc, removing the old
+	'conflict_report'.  Translate the entire conflict report at once,
+	so that we don't assume that "," has the same interpretation in
+	all languages.
+	(conflicts_output): Use Yacc-style conflict report for each state,
+	instead of our more-complicated style.
+	(conflicts_print): Use Yacc-style conflict report, except print
+	the input file name when not emulating Yacc.
+	* tests/conflicts.at (Unresolved SR Conflicts, Defaulted
+	Conflicted Reduction, %expect not enough, %expect too much,
+	%expect with reduce conflicts): Switch to Yacc-style conflict reports.
+	* tests/existing.at (GNU Cim Grammar): Likewise.
+	* tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
+
+	* src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
+	fatal): Don't invoke fflush; it's not needed and it might even be
+	harmful for stdout, as stdout might not be open.
+	* src/reduce.c (reduce_print): Likewise.
+
+2002-12-27  Paul Eggert  <eggert@twinsun.com>
+
+	Fix a bug where error locations were not being recorded correctly.
+	This problem was originally reported by Paul Hilfinger in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001901.html>.
+
+	* data/yacc.c (yyparse): New local var yylerrsp, to record the
+	top of the location stack's error locations.
+	(yyerrlab): Set it.  When discarding a token, push its location
+	onto yylerrsp so that we don't lose track of the error's end.
+	(yyerrlab1): Now is only the target of YYERROR, so that we can
+	properly record the location of the action that failed.  For GCC
+	2.93 and later, insert an __attribute__ ((__unused__)) to avoid
+	GCC warning about yyerrlab1 being unused if YYERROR is unused.
+	(yyerrlab2): New label, which yyerrlab now falls through to.
+	Compute the error's location by applying YYLLOC_DEFAULT to
+	the locations of all the symbols that went into the error.
+	* doc/bison.texinfo (Location Default Action): Mention that
+	YYLLOC_DEFAULT is also invoked for syntax errors.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+	Error locations include the locations of all the tokens that were
+	discarded, not just the last token.
+	
+2002-12-26  Paul Eggert  <eggert@twinsun.com>
+
+	* src/files.c: Include quote.h.
+	(compute_output_file_names): Warn if we detect conflicting
+	outputs to the same file.  This should catch the misunderstanding
+	exemplified by Debian Bug 165349, reported by Bruce Stephens..
+
+	* src/conflicts.c (conflicts_print): If the user specifies
+	"%expect N", report an error if there are any reduce/reduce
+	conflicts.  This is what the manual says should happen.
+	This fixes Debian bug 130890, reported by Anthony DeRobertis.
+	* tests/conflicts.at (%expect with reduce conflicts): New test.
+
+	Don't use m4_include on relative file names, as it doesn't work as
+	desired if there happens to be a file with that name under ".".
+	
+	* m4sugar/version.m4: Remove; it was included but it wasn't used.
+	* data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
+	* data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
+	* data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
+	* src/output.c (output_skeleton): Use full path names when
+	specifying a file to include; don't rely on include path, as
+	it's unreliable when the working file contains a file with
+	that name.
+	
+2002-12-25  Paul Eggert  <eggert@twinsun.com>
+
+	Remove obsolete references to bison.simple and bison.hairy.
+	Problem mentioned by Aubin Mahe in
+	<http://mail.gnu.org/pipermail/help-bison/2002-December/001765.html>.
+	* data/glr.c: Comment fix.
+	* doc/bison.1: Remove references.  Also, mention "yacc".
+
+	* src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
+	with -g option.
+
+	* src/parse-gram.y (declaration): Use enum "report_states" rather
+	than its numeric value 1.
+
+	* src/scan-skel.l ("@output ".*\n): Close any old yyout before
+	opening a new one.  This fixes Debian bug 165349, reported by
+	Bruce Stephens.
