+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.
+
+2002-11-27  Paul Eggert  <eggert@twinsun.com>
+
+	Rename identifiers to avoid real and potential collisions.
+
+	* data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
+	to avoid collision with lex macro described by Bruce Lilly in
+	<http://mail.gnu.org/pipermail/bug-bison/2002-November/001929.html>.
+	* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
+	* doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
+	* src/parse-gram.y (print_token_value): Renamed from yyprint.
+	All uses changed.
+	(YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove.  All uses changed.
+	The name "yycontrol" violates the name space rules, and this stuff
+	wasn't being used anyway.
+	(input): Remove action; this stuff wasn't being used.
+	(gram_error): Rename local variable yylloc -> loc.
+	* src/reader.h (struct gram_control_s, gram_control_t): Remove.
+	(YY_DECL): Don't use "yy" at start of local variables.
+	All uses changed, e.g., yylloc -> loc.
+	* src/scan-gram.l (STEP): Renamed from YY_STEP.  All uses changed.
+	(STRING_GROW): Renamed from YY_OBS_GROW.  All uses changed.
+	(STRING_FINISH): Renamed from YY_OBS_FINISH.  All uses changed.
+	(STRING_FREE): Renamed from YY_OBS_FREE.  All uses changed.
+
+	* src/parse-gram.y (gram_error): loc is now const *.
+	* src/reader.h (gram_error): Likewise.
