config/gould/tm-np1.h, hppa-tdep.c (hppa_fix_call_dummy), remote-vx.c:
Use REGISTER_SIZE, unsigned LONGEST, and
{store,extract}_unsigned_integer, instead of sizeof
(REGISTER_TYPE) and REGISTER_TYPE.
* All tm.h files: Change REGISTER_TYPE to REGISTER_SIZE.
* hppa-tdep.c (pa_print_fp_reg): Remove unused variable val.
* Makefile.in (ALLDEPFILES): Remove i386ly-nat.c and m68kly-nat.c.
Add lynx-nat.c.
