Re: Can't set architecture to m32c on m32c-elf-gdb.

> Renesas is planning to ship R32C series.

They're already shipping it.  It's as different from M32C as M32C is
from M16C (m16c/60 at least) - no opcode compatibility at all, aside
from a "passing resemblance" at the asm syntax level.

M16C vs R8C is much closer; they differ only in two opcodes.  M16C/80
vs M32C/80 have the same architecture, but m32c has more opcodes.

RX is a step up from R32C.  Same peripherals, basically, but
completely different opcodes and register set.
