* sysdeps/i386/bp-asm.h (PCOFF): New constant.
(POP_ERRNO_LOCATION_RETURN): Fold insns. 
* sysdeps/i386/bits/setjmp.h (JB_SIZE): New constant. 
(PUSH_SIGNAL_MASK): New macro. 
* sysdeps/i386/__longjmp.S (__longjmp): Wrap symbol in BP_SYM (). 
LEAVE is unnecessary.  Check bounds of jmp_buf. 
* sysdeps/i386/elf/setjmp.S: Call PUSH_SIGNAL_MASK.  Wrap symbols 
in BP_SYM ().  Check bounds of jmp_buf.  Don't call LEAVE until 
immediately before tail-call. 
* sysdeps/i386/setjmp.S: Likewise. 
* sysdeps/i386/bsd-_setjmp.S: Likewise.
