stupid g++ question

[gerry.feldman at compaq.com (Jerry Feldman)]

Interesting. I just copied over to a Red Hat system and it built fine. 
I have verified that the code does pick up the header files from the 
correct place. (On Tru64 /usr/local/include/g++-v3). I think the issue 
might have to do with one of the compile time switches.
