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.
