GCC3 is not supported in practice because no developer that I know of
uses it on a regular basis. However, there are still users using it
and as long as people care to write patches to fix support, I think
GCC3 support shouldn't be formally dropped.

The situation isn't that different than support of GCC2.95: few
developers use it, nevertheless people do fix it support from time to
time when a breakage is detected.
