Sat Oct 19 17:42:24 1996 Ulrich Drepper <drepper@cygnus.com> * intl/locale.alias: Language for entry `czech' is `cs'. Fri Oct 17 13:20:35 1996 Thorsten Kukuk <kukuk@weber.uni-paderborn.de> * sunrpc/etc.rpc: Update from ti-rpcsvc 2.3. Fri Oct 18 22:56:45 1996 Ulrich Drepper <drepper@cygnus.com> * sunrpc/Makefile (install-sbin): Remove portmap. This version is buggy and more competent people work on a usable version which is distributed separately. * sunrpc/portmap.c: Removed. Suggested by Thorsten Kukuk. Fri Oct 18 12:17:09 1996 Enrique Melero <justine@iprolink.ch> * sysdeps/libm-ieee754/s_finitel.c: Change function name to `finitel'. Fri Oct 18 00:01:10 1996 Ulrich Drepper <drepper@cygnus.com> * string/Makefile (tests): Add stratcliff. * string/stratcliff.c: New file. Test for string function at the edge of the usable memory. Thu Oct 17 22:10:19 1996 Ulrich Drepper <drepper@cygnus.com> * Makerules ($(libdir)/libc.so): Fix typo. * elf/ldd.sh.in: Test whether given file really exist and give better message if it is not available. Thu Oct 17 04:25:38 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sys/shm_buf.h: Add definition for SHM_R and SHM_W. * locale/programs/localedef.c (main): Test with -1 to find out
