I do run gcc, although I haven't done any substantial development.

I'm not sure if Jaffa has installed gcc more recently than I have, but my experiences about a month ago were not so simple -- had to downgrade a few packages because the SDK did not keep up with the SSUs, and all the -dev (headers) packages depend on the same exact version of the binaries.

Just be cautious if you do go that route, as you can install packages conflicting with dependencies of, oh, about half your system. (The critical half!) It'll ask you to confirm, of course, but don't blindly say yes; that's all.
