Thanks Thomas and Martin.  I did some reading up on the standard
namespace thing and I understand now.  Thank you both very much for
your responses!

I think I'll just convert the older programs to the standard c++
usage.

One additional question...what if I have a .h file that I wrote
myself...do I still include it as #include "foo.h"  or is it an
#include <foo>

Thanks!

Drew
