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.
