	DJGPP spefic issue.  Inhibit the use of disallowed characters for
	file name genertion on Win98, WinXP, etc.  These are |<>":?*\

	Miscellaneous %define and %code cleanup.
	* data/bison.m4 (b4_percent_define_flag_if): Correct comments on how
	values are interpreted.
	* doc/bison.texinfo (Decl Summary): Clean up and extend %define

	muscle_percent_define_insert and muscle_percent_code_grow when parsing
	%define and %code directives.

	Make it easy to share %define boolean variables between the front-end
	and back-end.  Though not used yet, this will be useful in the future.
	* data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
	Bison uses of names rather than just skeleton uses of names.
	(b4_percent_define_get, b4_percent_define_ifdef): Rename

	b4_percent_define_bison_variables(VARIABLE).

	b4_percent_code_bison_qualifiers(QUALIFIER).

	For %define variables, report locations for invalid values and
	redefinitions.
	* data/bison.m4 (b4_percent_define_flag_if): Read
	b4_percent_define_loc(VARIABLE) to report the location of an invalid
	value for VARIABLE.
	(b4_percent_define_default): Save a special location in
	b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
	must later be reported as invalid.
	* src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
	functions.

	muscle percent_define_loc(VARIABLE), and use it to report the previous
	location for a redefinition.

	(muscle_percent_define_default): Update like b4_percent_define_default.
	(muscle_grow_user_name_list): Rename to...
	(muscle_user_name_list_grow): ... this for consistency and use
