My concern is that we have the following versions of gcc in the tree: gcc-2.95.3-r10 gcc-3.3.6-r1 gcc-3.4.6-r2 gcc-4.0.4 gcc-4.1.2 gcc-4.2.4-r1 gcc-4.3.6-r1 gcc-4.4.7 gcc-4.5.4 gcc-4.6.4 gcc-4.7.4 gcc-4.8.5 gcc-4.9.3 gcc-4.9.4 gcc-5.4.0 gcc-5.4.0-r3 gcc-6.3.0 Under your proposal, I guess we would just have gcc-5.4.0-r3, gcc-4.9.4 and maybe gcc-3.4.6-r2 and *definitely maybe* gcc-2.95.3-r10. Is this correct?
