Sorry about that, we weren't aware that there were any remaining OSF/1
users.

Try the following: first patch configure with the attached patch.  Then,
take the file src/s/osf1.h from Emacs 22.3 (I can send it to you by
attachment if you can't find it) and put it in the src/s/ directory.

Then try to build.  If that works, we can put OSF/1 support back in for
Emacs 23.2.
