  Also, apologies: there was a packaging hiccup in the latest version, and the
execute permissions got lost.  If you try to just run set-gcc-default-[34].sh
at the shell, you'll get a "Permission denied" error; you can either chmod a+x
them, or use the ". <name>" (aka bash "source" builtin) syntax to invoke them.

    cheers,
