[M3devel] Are all 5 gcc branches used?

[John Marino]

I see 5 gcc branches in m3-sys/m3cc.  I've seen gcc-4.7 in use and I can
guess gcc-apple is still used, but are gcc, gcc-4.5, and gcc-4.6
branches obsolete?

There reason why it matters is that I'm using github's built-in "create
tarball from top of repo" capability as the digest-confirmed source
distribution file.  All the extra gcc branches are causing the
compressed tarball to be pretty big.  Currently it's at 150Mb.

If some of these gcc branches are unused and will never again be used, I
might suggest they are pruned.  It's in the repository so they could be
retrieved with the right hash, and it would dramatically reduce the size
of the archive tarball.

If all 5 versions of gcc are still used then that's a horse of a
different color.
