openssh on NeXTstep

[Ben Lindstrom]

Right.. Right.. I didn't see it when I running cpp over the file since for
some reason my preproccessor under Linux didn't change signal() to
mysignal() in bsd-misc.c, but there should be an #undef signal before the
return(signal(..)) to ensure the real signal gets used.

I'm still puzzled why NeXT triggers this because NeXT's signal() has too
loose of sementics for what we want and it should have defaulted to using
the HAVE_SIGACTION.

I remember having to dig around for a tolerable replacement for NeXT

- (djm) More NeXT compatibility from Ben Lindstrom <mouring at pconline.com>
   Including sigaction() et al. replacements

This troubles me greatly.
