Comment (by mascguy):

 Replying to [comment:8 kencu]:
 > we do need to keep the older gcc versions for other purposes, and
 probably the older clangs too for similar reasons (bootstrapping or
 certain older code that needs it and can't/won't be updated).

 Ken, are you referring to MacPorts as a whole, or just these two ports? I
 ask, as I'm speaking just for the latter...
