88K changes inspired by Ted Lemon (uunet!lupine!mellon)
* tm-m88k.h, tm-umax.h: Avoid sizeof() in REGISTER_xxx macros, since they define the target, not the host. * m88k-pinsn.c: Fix typo. Patches by Paul Eggert <eggert@twinsun.com>. * valarith.c (value_zerop): -0.0 is still zero. * eval.c (evaluate_subexp): Avoid NaN anomalies in float compares.
