	Don't link against -liberty.
	(gencode.o, getopt.o, getopt1.o): New targets.
	* gencode.c: Include <ctype.h> and "ansidecl.h".
	(AND): Undefine after including "ansidecl.h".
	(ULONG_MAX): Define if not defined.
	(OP_*): Don't define macros; now defined in opcode/mips.h.
	(main): Call my_strtoul rather than strtoul.
	(my_strtoul): New static function.

Wed Jul 17 18:12:38 1996  Stu Grossman  (grossman@critters.cygnus.com)

	* gencode.c (process_instructions):  Generate word64 and uword64
	instead of `long long' and `unsigned long long' data types.
	* interp.c:  #include sysdep.h to get signals, and define default
	for SIGBUS.
	* (Convert):  Work around for Visual-C++ compiler bug with type
	conversion.
	* support.h:  Make things compile under Visual-C++ by using
	__int64 instead of `long long'.  Change many refs to long long
	into word64/uword64 typedefs.
