+	For consistency, remove _e and _s endings -- they're weren't
+	needed to remove ambiguity.  All uses changed.

+	* tests/input.at (Torturing the Scanner): Rename value_t -> value,
+	value_t_as_yystype -> value_as_yystype.
+
+	Don't include <errno.h> in the mainstream code, since it
+	reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
+	* lib/get-errno.c, lib/get-errno.h: New files.
+	* lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
+	get-errno.c.

+	* src/uniqstr.c: Renamed from src/struniq.c.

+	for consistency with other names.
+	* lib/timevar.h (timevar_report): New decl.
+	* src/system.h (time_report): Remove; decl is now in lib/timevar.h.
+
+
+	Sort include-file uses.
+
+	Reorder all include files under src to be in the order "system.h".
+	then the ../lib include files in angle brackets (alphabetized),
+	then the . include files in double-quotes (alphabetized).  Fix
+	dependency breakages encountered in this process, as follows:
+	* src/closure.h, src/derives.h, src/state.h: Include "gram.h".
+	* src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
+	* src/state.h: Include "symtab.h".
+
+2002-12-08  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
+	since this causes problems when __file__ contains character
+	sequences like "@" that are treated specially by src/scan-skel.l.
+	Instead, just use the file's basename.  This fixes the bug
+	reported by Martin Mokrejs in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-December/001945.html>.
+
+2002-12-06  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for rules that do not have trailing semicolons, as
+	POSIX requires.  Improve the quality of locations in Bison
+	diagnostics.
+
+	* src/location.c: Include <quotearg.h>.
+	(empty_location): Now const.
+	(location_print): New function.  Follow the recommendation of the
+	GNU Coding Standards for locations that span file boundaries.
+	* src/location.h: Do not include <quotearg.h>; no longer needed.
+	(boundary): New type.
+	(location_t): Use it.  This allows locations to span file boundaries.
+	All member uses changed: file -> start.file or end.file (as needed),
+	first_line -> start.line, first_column -> start.column,
+	last_line -> end.line, last_column -> end.column.
+	(equal_boundaries): New function.
+	(LOCATION_RESET, LOCATION_STEP): Remove.
+	(LOCATION_PRINT): Remove.  All callers changed to use location_print.
+	(empty_location): Now const.
+	(location_print): New decl.
+	* src/parse-gram.y (lloc_default): New function, which handles
+	empty locations more accurately.
+	(YYLLOC_DEFAULT): Use it.
+	(%token COLON): Remove.
+	(%token ID_COLON): New token.
+	(rules): Use it.
+	(declarations, rules): Remove trailing semicolon.
+	(declaration, rules_or_grammar_declaration):
+	Allow empty (";") declaration.
+	(symbol_def): Remove empty actions; no longer needed.
+	(rules_or_grammar_declaration): Remove trailing semicolon.
+	(semi_colon.opt): Remove.
+	* src/reader.h: Include location.h.
+	(scanner_cursor): New decl.
+	* src/reduce.c (nonterminals_reduce): Use warn_at rather than
+	rolling our own.
+	* src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
+	of *loc.
+	(STEP): Remove.  No longer needed, now that adjust_location does
+	the work.  All uses removed.
+	(scanner_cursor): New var.
+	(adjust_location): Renamed from extend_location.  It now sets
+	*loc and adjusts the scanner cursor.  All uses changed.
+	Don't bother testing for CR.
+	(handle_syncline): Remove location arg; now updates scanner cursor.
+	All callers changed.
+	(unexpected_end_of_file): Now accepts start boundary of token or
+	comment, not location.  All callers changed.  Update scanner cursor,
+	not the location.
+	(SC_AFTER_IDENTIFIER): New state.
+	(context_state): Renamed from c_context.  All uses changed.
+	(id_loc, code_start, token_start): New local vars.
+	(<INITIAL,SC_AFTER_IDENTIFIER>): New initial context.  Move all
+	processing of Yacc white space and equivalents here.
+	(<INITIAL>{id}): Save id_loc.  Begin state SC_AFTER_IDENTIFIER
+	instead of returning ID immediately, since we need to search for
+	a subsequent colon.
+	(<INITIAL>"'", "\""): Save token_start.
+	(<INITIAL>"%{", "{", "%%"): Save code_start.
+	(<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
+	(<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
+	BEGIN context_state at end, not INITIAL.
+	(<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
+	<SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
+	Return correct token start.
+	(<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
+	the start of a character, string or multiline comment is found.
+	* tests/conflicts.at (S/R in initial, Defaulted Conflicted
+	Reduction): Adjust reported locations to match the more-precise
+	results now expected.
+	* tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
+	* tests/reduce.at (Useless Rules, Reduced Automaton,
+	Underivable Rules): Likewise.
+	* tests/regression.at (Invalid inputs): No longer `expecting ";"
+	or "|"' now that so many other tokens are allowed by the new grammar.
+
+	* src/complain.h (current_file): Remove duplicate decl;
+	current_file is now owned by files.h.
+	* src/complain.c, src/scan-gram.l: Include files.h.
+
+2002-12-06  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
+	promotes to int; it might be unsigned int.
+	* data/yacc.c (yy_reduce_print): Likewise.
+
+	* doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
+	be #defined in the prologue, not in the Bison declarations.
+	This fixes Debian Bug 102878, reported by Shaul Karl.
+
+2002-12-02  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.ac (AC_REPLACE_FUNCS): Add strtoul.
+	* lib/strtoul.c: New file, from gnulib.
+	This fixes a porting bug reported by Peter Klein in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-December/001944.html>.
+
+2002-11-30  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
+	and put only a forward declaration in the prologue.  This is for
+	consistency with the other scanner helper functions.
+
+	Type clashes now generate warnings, not errors, since it
+	appears that POSIX may allow some grammars with type clashes.
+	* src/reader.c (grammar_current_rule_check): Warn about
+	type clashes instead of complaining.
+	* tests/input.at (Type Clashes): Expect warnings, not complaints.
+
+	Add Yacc library, since POSIX requires it.
+	* doc/bison.texinfo (Yacc Library): New node.  Regenerate top menu.
+	* lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
+	* lib/main.c, lib/yyerror.c: New files.
+
+	gram_error can be static; it need not be extern.
+	* src/reader.h (gram_error): Remove decl.
+	* src/parse-gram.y (gram_error): Now static.  Add static decl.
+	(print_token_value): Omit parameter names from forward decl,
+	for consistency.
+
+2002-11-29  Paul Eggert  <eggert@twinsun.com>
+
+	* doc/bison.texinfo: Emphasize that yylex and yyerror must
+	be declared before being used.  E.g., one should typically
+	declare them in the prologue.  Use GNU coding style in examples.
+	Put "const" consistently after the type it modifies.  Mention
+	that C99 supports "inline".  Mention that yyerror traditionally
+	returns "int".
+
+	%parse-param and %lex-param now take just one argument, the
+	declaration; the argument name is deduced from the declaration.
+
+	* doc/bison.texinfo (Parser Function, Pure Calling, Error
+	Reporting, Table of Symbols): Document this.
+	* src/parse-gram.y (add_param): New function.
+	(COMMA): Remove.
+	(declaration): Implement new rule for %parse-param and %lex-param.
+	* src/scan-gram.l: "," now elicits a warning, rather than being
+	a token; this is more compatible with byacc.
+	* tests/calc.at (Simple LALR Calculator): Adopt new convention.
