Recently, a change was made to git/Makefile to invoke "uname -o". This isn't portable to OSX/Darwin. Is there a chance this information can be obtained some other way, or not invoked on darwni?

Peter, I noticed the same on Solaris recently.

The following seems to work but is quite yucky, and I prefer somebody to come up with a better alternative.

How about a chain of elsif's?
Doesn't make support that?
I mean, when you know it's Darwin, no point in checking if it's OpenBSD. :)
