Subject: * Makefile.in (ALLDEPFILES): Remove alphanbsd-nat.c.
 (alphanbsd-nat.o): Remove dependency list. (alphanbsd-tdep.o): Add
 $(regcache_h) to dependency list. * alphanbsd-nat.c: Delete.  Contents moved
 to... * alphanbsd-tdep.c: ...here. (_initialize_alphanbsd_tdep): Register
 core functions. * config/alpha/nbsd.mh (NATDEPFILES): Remove alphanbsd-nat.o.
