That's amazing, Markus! You rock!

I think it is. However, we should think about the design a bit first:

1. Should it be based on a more general mechanism for replacing the built-in
standard library?
2. Shall we arrange things so that you can build both with and without
stlport, and such that each build goes in a separate subvariant directory?

Hmm, I'm not sure there are ever any STLPort revisions that preserve link
compatibility.

Good question.

For the most part, stl_user_config is no longer supported, IIRC. I think the
only thing worth supporting (and even this is arguable, since it doesn't
really work well) is STLP_NO_IOSTREAMS. But maybe I've overlooked something?
