* 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.
