	(struct modebyte): Don't use.
	(vax_operandmode): Pass in an unsigned char *.
	(vax_operandlength): Likewise.
	(vax_reladdr): Rename to vax_offset and return relative offset
	rather than address.
	* i386.c (i386_find_call): Avoid casts between pointers and
	integers of different sizes.
	* sparc.c (sparc_find_call): Likewise.  Avoid endian problems.
	* tahoe.c (tahoe_find_call): Likewise.
