* config/rs6000/tm-rs6000.h (FPLAST_REGNUM): Delete #definition. 

* ppc-tdep.h (ppc_num_fprs): New enum constant.
* aix-thread.c (fetch_regs_kernel_thread, fill_fprs,
store_regs_kernel_thread): Use FP0_REGNUM + ppc_num_fprs, not
FPLAST_REGNUM.
* ppc-bdm.c (bdm_ppc_fetch_registers, bdm_ppc_store_registers):
Same.
* ppc-linux-nat.c (ppc_register_u_addr): Same.
* rs6000-nat.c (regmap, fetch_inferior_registers)
(store_inferior_registers): Same.
