1999-07-06 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/alpha/ioperm.c: Update for some more motherboards. Patch by Jay Estabrook. * sysdeps/unix/sysv/linux/configure.in: Don't test for libc4 in ldd for SPARC. * /sysdeps/unix/sysv/linux/sparc/ldd-rewrite.sed: New file. Patch by Cristian Gafton. 1999-07-02 Cristian Gafton <gafton@redhat.com> * sysdeps/unix/sysv/linux/bits/socket.h (__cmsg_nxthdr): "return 0" instead of "return NULL" to make C++ happy. 1999-07-04 Mark Kettenis <kettenis@gnu.org> * libio/iofdopen.c (_IO_new_fdopen): Set EINVAL if MODE is not allowed by the file access mode of the open file. 1999-07-06 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/setfpucw.c: Include math.h to get all needed macros defined. 1999-07-03 Jakub Jelinek <jj@ultra.linux.cz> * sysdeps/sparc/sparc64/submul_1.S: Fix carry handling. Optimize. * sysdeps/sparc/sparc64/lshift.S: Make a leaf subroutine.
