* config/nm-nbsd.h (FETCH_INFERIOR_REGISTERS): Defined.

Browse Source 
* config/xm-nbsd.h (CC_HAS_LONG_LONG, PRINTF_HAS_LONG_LONG):
#ifdef'd out definitions ---  Causes serious gdb failures on
the i386.  Need to investigate further before enabling.

* i386b-nat.c (fetch_inferior_registers, store_inferior_registers,
fetch_core_registers): New functions.  These functions are defined
if FETCH_INFERIOR_REGISTERS is set.  Registers are fetched/stored
with ptrace PT_GETREGS/PT_SETREGS.
