I haven't tried using it myself, but this is frequently asked on the
MinGW mailing list, and the answer always seems to be negative.

Perhaps I'm confusing std::wstring with std::wiostream :

Or perhaps not:

Maybe the MinGW issues will be resolved by the time they actually
matter to us (e.g., when wx-3.0 is released); I don't think we need
to take much more action now, though I plan to apply Vadim's concrete
suggestions (in another message--e.g., LoadLibraryA()) soon.
