The above is really, really ugly, not to say broken, because neither
being on a Sun nor using gcc have anything to do with whether your
compiler handles namespaces.  The problem we are looking at here is that
the C++ standard is a moving target, and some people have compilers that
are newer than others.

I think the proper solution is to add a configure-time test to see
whether a namespace declaration is needed.  We could use configure to
see whether we need ".h" on the end of C++ include file references, too.
(That's another thing that's going to be site-dependent for a while to
come.)
