Update.
2003-04-12 Ulrich Drepper <drepper@redhat.com> * sysdeps/generic/dl-tls.c (_dl_allocate_tls_init): Add cast to avoid warning. * sysdeps/unix/sysv/linux/i386/sigaction.c (__libc_sigaction): If __ASSUME_VSYSCALL is defined don't add restorer. * sysdeps/unix/sysv/linux/kernel-features.h: Define __ASSUME_VSYSCALL for 2.5.53.
