11 gcc is the full-blown GNU compiler. This is what most people will choose.
13 gcc supports many languages, a powerful code parser, optimised binary
14 output, and lots of other features.

19 depends on EXPERIMENTAL
21 Linaro is maintaining some advanced/more stable/experimental versions
22 of gcc, especially for the ARM architecture.
24 Those versions have not been blessed by the gcc comunity (nor have they
25 been cursed either!), but they look to be pretty much stable, and even
26 more stable than the upstream versions. YMMV...
28 If you do not know what this Linaro stuff is, then simply say 'n' here,
29 and rest in peace. OTOH, if you know what you are doing, you will be
30 able to use and enjoy :-) the Linaro versions by saying 'y' here.
