2002-12-17 Jakub Jelinek <jakub@redhat.com> * malloc/thread-m.h (mutex_init, mutex_lock, mutex_trylock, mutex_unlock): If not building NPTL, use __libc_maybe_call2 if available, otherwise __libc_maybe_call. * sysdeps/unix/sysv/linux/x86_64/recv.c: Add support for cancellation handling. * sysdeps/unix/sysv/linux/x86_64/send.c: Likewise.
