+
+	Equip the skeleton chain with location tracking, runtime trace,
+	pure parser and scanner.
+
+	* src/parse-skel.y: Request a pure parser, locations, and prefix
+	renaming.
+	(%union): Having several members with the same type does not help
+	type mismatches, simplify.
+	(YYPRINT, yyprint): New.
+	(yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
+	(skel_error): this.
+	Handle locations.
+	* src/scan-skel.l: Adjust to these changes.
+	* src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
+	(LOCATION_PRINT, skel_control_t): New.
+
+2001-12-30  Akim Demaille  <akim@epita.fr>
+
+	* src/parse-skel.y: Get rid of the shift/reduce conflict:
+	replace `gb' with BLANKS.
+	* src/scan-skel.l: Adjust.
+
+	
+2001-12-30  Akim Demaille  <akim@epita.fr>
+
+	* src/system.h: We don't need nor want bcopy.
+	Throw away MS-DOS crap: we don't need getpid.
+	* configure.in: We don't need strndup.  It was even causing
+	problems: because Flex includes the headers *before* us,
+	_GNU_SOURCE is not defined by config.h, and therefore strndup was
+	not visible.
+	* lib/xstrndup.c: New.
+	* src/scan-skel.l: Use it.
+	Be sure to initialize yylval.muscle member when scanning a MUSCLE.
+	* src/parse-skel.y: Use %directives instead of #defines.
+
+	
+2001-12-30  Akim Demaille  <akim@epita.fr>
+
+	* src/skeleton.h: New.
+	* src/output.c (output_parser, output_master_parser): Remove, dead
+	code.
+	* src/output.h (get_lines_number, actions_output, guards_output)
+	(token_definitions_output): Prototype them.
+	* src/parse-skel.y: Add the license notice.
+	Include output.h and skeleton.h.
+	(process_skeleton): Returns void, and takes a single parameter.
+	* src/scan-skel.l: Add the license notice.
+	Include skeleton.h.
+	Don't use %option yylineno: it seems that then Flex imagines
+	REJECT has been used, and therefore it won't reallocate its
+	buffers (which makes no other sense to me than a bug).  It results
+	in warnings for `unused: yy_flex_realloc'.
+

+
+	* src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
+	(MUSCLE_INSERT_PREFIX): ...to there.
+	* src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
+	(MUSCLE_INSERT_PREFIX): Move from here...
+
+	* src/bison.hairy: Add a section directive.  Put braces around muscle
+	names.  This parser skeleton is still broken, but Bison should not
+	choke on a bad muscle 'syntax'.
+	* src/bison.simple: Add a section directive.  Put braces around muscle
+	names.
+
+	* src/files.h (strsuffix, stringappend): Add declarations.
+	(tab_extension): Add declaration.
+	(short_base_name): Add declaration.
+
+	* src/files.c (strsuffix, stringappend): No longer static.  These
+	functions are used in the skeleton parser.
+	(tab_extension): New.
+	(compute_base_names): Use the computations done in this function
+	to guess if the generated parsers should have '.tab' in their 
+	names.
+	(short_base_name): No longer static.
+
+	* src/output.c (output_skeleton): New.
+	(output): Disable call to output_master_parser, and give a try to
+	a new skeleton handling system.
+	(guards_output, actions_output): No longer static.
+	(token_definitions_output, get_lines_number): No longer static.
+
+	* configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
+
+	* src/Makefile.am (bison_SOURCES): Add scan-skel.l and 
+	parse-skel.y.
+
+	* src/parse-skel.y: New file.
+	* src/scan-skel.l: New file.

 	%name-prefix is broken.
