I presume you mean mingw with gcc 3?

This could well be a serious issue as we use new() currently. I hate to
suggest it, but maybe having a contributed cross-compile package really
is the way to go. Sure, it'll massively increase
build-cross-compile-from-scratch overhead (build cygwin target, build
mingw target, build cygwin hosted) ....

I suspect that we'll need a mingw target cross compiler to generate the
correct threading model for libstc++ at a minimum.
