Update.
2003-09-02 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/i386/not-cancel.h: New file. * sysdeps/unix/sysv/linux/x86-64/not-cancel.h: New file. * sysdeps/unix/sysv/linux/i386/lowlevellock.h: Make sure the code in subsections has a symbol associated with it. * sysdeps/unix/sysv/linux/i386/sysdep-cancel.h (PSEUDO): Also defined symbol for entry point to avoid cancellation. * sysdeps/unix/sysv/linux/x86_64/sysdep-cancel.h (PSEUDO): Likewise.
