* mips.c (gpr_mode): New variable.
(override_options): Initialize gpr_mode.
(compute_frame_size): Use "gpr_mode" instead of "word_mode" to
determine size and offset of general purpose registers save slots.
(save_restore_insns, mips_expand_prologue): Similarly.
* Makefile.in (LIB2FUNCS_EH): Define. Just "_eh" for now.
(LIBGCC2_CFLAGS): Remove -fexceptions.
(LIB2FUNCS): Remove "_eh".
