1998-06-03 03:09 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/pread.c: Detect missing syscall, like poll(). * sysdeps/unix/sysv/linux/pread64.c: Likewise. * sysdeps/unix/sysv/linux/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/pwrite64.c: Likewise. 1998-06-03 03:09 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/powerpc/Makefile: Use -G0 on the startup file; this makes it easier to undump emacs. * sysdeps/powerpc/bits/endian.h: Use more informative error message for when the endianness can't be determined. 1998-06-04 13:19 Geoff Keating <geoffk@ozemail.com.au> * nss/Makefile: Add files publickey database support. * nss/libnss_files.map: Export the required functions. * nss/nss_files/files-key.c: Implement it. * sunrpc/rpc/auth_des.h: Correct typos in comments.
