* i386bsd-nat.c: Include "gregset.h". 

(CANNOT_STORE_REGISTER): Define to cannot_fetch_register instead
of CANNOT_FETCH_REGISTER, if not already defined.
(supply_gregset): Call supply_register with NULL as its second
argument instead of supplying our own zeroed out buffer.
(fill_gregset): Copy contents of correct registers instead of the
contents of register REGNO.
