     help

       Linaro is maintaining some advanced/more stable/experimental versions

       of gcc, especially for the ARM architecture.

       Those versions have not been blessed by the gcc comunity (nor have they

       been cursed either!), but they look to be pretty much stable, and even

       more stable than the upstream versions. YMMV...

       If you do not know what this Linaro stuff is, then simply say 'n' here,

       and rest in peace. OTOH, if you know what you are doing, you will be

       able to use and enjoy :-) the Linaro versions by saying 'y' here.

       from http://gcc.gnu.org/svn/gcc, if you are behind a proxy or firewall.

       By default, the gcc download will be an export of the subversion

       Note that crosstool-NG will *not* update your working copy, you will

       have to do that yourself.
