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