Sat Sep 30 11:47:05 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* posix/tstgetopt.c, posix/tstgetopt.args: Test long options too. * sysdeps/unix/sysv/linux/i386/init-first.c (init): Save, set, and restore %ebx by hand for personality syscall. GCC cannot deal with spilling the dedicated GOT register. * misc/Makefile (routines): Add mntent, which was somehow omitted. Fri Sep 29 15:07:10 1995 Ulrich Drepper <drepper@ipd.info.uni-karlsruhe.de> * sysdeps/unix/sysv/linux/adjtime.c (__adjtime): Change name of field `mode' in `struct timex' to `modes'. Linux-1.3.28 updates this name according to RFC 1489.
