If you upgrade the version of yum you are using (the version in RHEL-5.2 might be enough, but 5.4+ would be better) you can run:

yum --showduplicates list gcc

...and then install/upgrade/downgrade to a specific version. If the version you want isn't available in RHEL, then I'd seriously caution against using it ... however even then you should be able to download the rpm manually and use "yum downgrade gcc-blah.rpm" (or install/etc) to move to it.
