+ * 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.
