2003-04-11 Ulrich Drepper <drepper@redhat.com> * sysdeps/generic/libc-start.c: Cleanup MAIN_AUXVEC_ARG handling. Remove HAVE_CANCELBUF code. Replace with code using the new initializers for unwind-based cleanup handling. * sysdeps/generic/unwind.h: Update from latest gcc version. * sysdeps/unix/sysv/linux/i386/sysdep.h: Define labels in a few places to allow unwind data generation. * sysdeps/i386/bits/setjmp.h: Allow file to be included multiple times. * sysdeps/x86_64/bits/setjmp.h: Likewise. * sysdeps/sh/bits/setjmp.h: Likewise. * sysdeps/powerpc/bits/setjmp.h: Likewise. * sysdeps/unix/sysv/linux/ia64/bits/setjmp.h: Likewise. * sysdeps/alpha/bits/setjmp.h: Likewise.
