Log message:
	Changes in response to error report by S. Eken: GLR mode does not
	handle negative $ indices or $ indices in embedded rules correctly.
	See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
	
	(b4_rhs_value): Change to use YYFILL macro.
	(b4_rhs_location): Ditto.
	(yyfill): New function to copy from stack tree into array
	incrementally.
	(yyuserAction): Modify to allow incremental move of semantic values
	to rhs array when in GLR mode.
	Define YYFILL to use in user-defined actions to fill semantic array
	as needed.
	Remove dummy use of yystack, as there is now a guaranteed use.
	(yydoAction): Modify to allow incremental move of semantic values
	to rhs array when in GLR mode.
	(yyresolveAction): Ditto.
	(yyglrShiftDefer): Update comment.
