On my Mac with uuid-ossp 1.6.2 installed in /usr/local, configure whines
as shown above but the build goes through just fine, which probably is
because uuid-ossp.c doesn't try to include <unistd.h>. So the conflict
noted by configure doesn't really affect us AFAICS. I would say that
if there's anything to be done about it, it's the uuid-ossp folks'
problem to solve not ours.
