I have used multiple versions of gcc for years (mostly under
redhat/fedora) and have had good luck with installing a new version
under the default /usr/local but using the configure option
'--program-suffix=-X.Y.Z' where the 'X.Y.Z' is the version number.

Then i can use 'gcc-X.Y.Z' or the default 'gcc' as desired, and I've
never had any conflicts beteen the various versions.

P.S.  And as Rup mentioned, I NEVER build in the gcc source directory.
