Niether. It is 3.2 . The -1 is a mandrake package version, i.e.,
    version 1 of the gcc 3.2 package.

What does /usr/local/bin/gcc -v show?

Mandrake (and most other linux distros) slices and dices gcc into
    several packages. If you just hit the checkbox for gcc (on install),
    you don't get g++.

I suspect you have gcc 3.2.2 installed under /usr/local, with support
    for all languages, etc that are on by default, and gcc 3.2
    installed (by your linux distro) in /usr, with only the C
    frontend. Further, I guess /usr/bin comes before /usr/local/bin in
    your path. So typing 'gcc' results in /usr/bin/gcc, while 'g++'
    results in /usr/local/bin/g++, because you have no /usr/bin/g++.

If you installed gcc-3.2.2 from source, rpm will not be able to find
    it.
