Which arch is using gcc-3.3 as the default compiler?

["Marcelo E. Magallon" <mmagallo@debian.org>]

       * several-packages (0.1-1 to 0.2-1)
            + ...
            + Depends: gcc-3.2
            + Depends: gcc-3.3

 what's with that?  And what's with the ones that _don't_ depend on
 gcc-3.3 but only on gcc-3.2?  Do they need a recompile on this
 architecture?

 Thanks,

 Marcelo
