* 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.
