2002-10-15* sysdeps/generic/dl-tls.c (_dl_deallocate_tls) [TLS_TCB_AT_TP]:Roland McGrath
Adjust TCB pointer before calling free, so we get the whole block. 2002-10-14 Roland McGrath <roland@redhat.com> * sysdeps/unix/sysv/linux/x86_64/sigaction.c [HAVE_HIDDEN && !HAVE_BROKEN_VISIBILITY_ATTRIBUTE]: Declare restore_rt extern using attribute_hidden instead of static, avoids warning.
