Update.

2003-08-27  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/x86_64/fpu/bits/mathinline.h: Define __signbitf,
	__signbit, and __signbitl inline functions.

	* sysdeps/unix/sysv/linux/x86_64/__start_context.S: Use
	HIDDEN_JUMPTARGET instead of JUMPTARGET to call exit().

	* sysdeps/x86_64/bsd-_setjmp.S [PIC]: Jump to __GI___sigsetjmp.
	* sysdeps/x86_64/setjmp.S: Add libc_hidden_def for __sigsetjmp.
