2003-03-20  Alexandre Oliva  <aoliva@redhat.com>

	* sysdeps/mips/bits/setjmp.h: Store all N32 and N64 registers,
	including pc, gp, sp and fp, as long long.
	* sysdeps/mips/mips64/setjmp.S: Pass gp to __sigsetjmp_aux.
	* sysdeps/mips/mips64/setjmp_aux.c: Adjust type of arguments.
	Add gp argument, and set gp in the jmpbuf to it.
	* sysdeps/mips/setjmp_aux.c: Revert to o32-only.
