2002-02-14 Ulrich Drepper <drepper@redhat.com> * stdlib/test-a64l.c (tests): Add more test cases. * sunrpc/rtime.c (rtime): Change type of thetime to uint32_t. Reported by Walter Harms <WHarms@bfs.de>. 2002-02-11 Jes Sorensen <jes@trained-monkey.org> * sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h: Add sc_flag bit definitions for struct sigcontext. Suggested by David Mosberger-Tang.
