Sorry I haven't got back to you sooner as I've been working on the problem.
As far as your gcc47-compiler & gcc47-runtime packages goes I'm totally
against committing them to the tree as there are so many problems with them
(I won't go in to detail because of the number) that it would not only
cause a significant number of build problems on different OS's but it
would make maintenance a nightmare!
Having siad that I've come up with a much much simpler and less disruptive
approach (if a little bit hackish) for having a package that contains just
the support libraries that I am happen to commit to the tree straight away
f you want?
As for my idea as to how to get around the USE_LIBTOOL/USE_GCC_RUNTIME stuff
I haven't had time to dig into that yet.

I think a better long term solution for that problem and the circular
dependency problem with USE_PKGSRC_GCC is to have a gcc-bootstrap package
that builds just the c complier.
