* i386v4-nat.c (supply_gregset, fill_gregset): Subtract NUM_FREGS

 	from NUM_REGS to get number of general registers that we care about.
	Update copyright to 1996.
	* config/i386/tm-i386.h (REGISTER_BYTES): Define in terms
	of number of general regs and number of floating point regs.
	Update copyright to 1996.
