I no longer have any redhat 7.2 systems, but I vaguelly recall that Red Hat had
gcc3 packages that would install the compiler as gcc3 instead of 'gcc'.  You
would also have to install any updated C++ libraries.

The simplest approach would be to upgrade to Red Hat 9, which has gcc 3.2.2
installed.

An alternative approach is to build the 3.3 compiler yourself, using the:

	--prefix=<somedir>

where <somedir> is some directory on your system, and then use
<somedir>/bin/gcc to build stuff with gcc 3.3 compiler.  If you use C++, you
will have to build any libraries used with the new release and use the
appropriate -L and -I options to use those libraries.
