ACE 5.2.1 and ACE 5.2 build errors with gcc 3.1 pre-release installover gcc 3.0.4

This is more of an FYI than anything else.

I tried to build ACE 5.2 and ACE 5.2.1 on a Red Hat 7.2 box with a 
previous build of gcc 3.0.4 installed in /usr/local.  The error (below) 
indicated a problem with the g++-v3 headers. So, I cleaned out the gcc 
3.0.4 headers by removing /usr/local/include/g++-v3 and I re-installed 
3.1PR and the ACE 5.2.1 build was ok.

I did a quick sqiz over the docs and found nothing that talks about this.

This is one of the multiple (same) errors I got when I built with a gcc 
3.1PR was installed over 3.0.4.
