Does Wendy's patch work?  I'd rather use her's.

applied.

Can we put this in defines.h instead?

I still want Markus or someone in the OpenBSD group to bless this or
come up with a high-breed idea for the OpenBSD tree.

This was commited to the upstream tree.

Still not included.  Waiting for feed back from others..

Applied most.

I can get Damien or someone else agree this is what we want to do?  It
looks fine to me.

Applied.

I added bsd-cray.h to openbsd-compat.h  where it should be.. If does not
work out there then we should try defines.h before putting it into a
single file.
