I found the following entry in winsup/cygwin/ChangeLog:

 2001-11-27  Christopher Faylor  <cgf@redhat.com>
 
         * cygwin.din (ualarm): New export.
         (ualarm): New function.  From Alexandr V. Shutko.

It looks like the unistd.h header never got updated; here is a small patch to
/usr/include/sys/unistd.h which seems to fix the compiling:

--- unistd.h.old        Thu Dec  6 12:17:06 2001

You're right.  That was my problem.  You can probably see what I did.  I just
duplicated the usleep line and (apparently) halfheartedly edited for ualarm.

I've patched newlib (the ChangeLog entry is in your name), so the next release
will have the proper prototype.

Thanks for the patch.
