First off, please consider this squashed in with my previous patch:

@end example
Apart from timestamp resolution, there are also differences in handling
-equal timestamps. HP-UX @command{make} updates targets if it has the
+equal timestamps. HP-UX @command{make} updates a target if it has the
same time stamp as one of its prerequisites, in violation of Posix rules.
Then, ok to apply the patch below as well? sh exits upon
read line < unreadable
or
read line < nonexistent
Luckily, ksh doesn't do this, otherwise libtool would've been in
trouble.
Thanks,
Ralf
