* Makefile.in (ALLDEPFILES): Add alphabsd-tdep.c.

Browse Source 
(alphabsd-nat.o): Depend on alphabsd-tdep.h.
(alphanbsd-nat.o): Likewise.
(alphabsd-tdep.o): New dependency list.
* alphabsd-nat.c (supply_gregset): Use alphabsd_supply_reg.
(fill_gregset): Use alphabsd_fill_reg.
(supply_fpregset): Use alphabsd_supply_fpreg.
(fill_fpregset): Use alphabsd_fill_fpreg.
(fetch_inferior_registers): Use struct reg and struct fpreg
rather than gregset_t and fpregset_t.  Use alphabsd_supply_reg
and alphabsd_supply_fpreg.
(store_inferior_registers): Use struct reg and struct fpreg
rather than gregset_t and fpregset_t.  Use alphabsd_fill_reg
and alphabsd_fill_fpreg.
