>Description:
	gengtype-yacc.y grammar definition file contains token definition
	lines which appear to be bison specific. The string values after the
	token are not supported by the stock FreeBSD yacc and they are not
	required for the parser to work anyway. Attached patch removes
	these string identifiers to facilitate easier integration of the
	upcoming GCC 3.3 release into FreeBSD source tree.

	Also, add defines for malloc and realloc to change them into
	xmalloc and xrealloc respectively. This takes care of yacc
	programs whose genererated code contains invocations of any
	of these functions.
>How-To-Repeat:
	N/A
