Proposed Boost.AFIO is also seeing segfaults on Mingw only

I had assumed it's the fault of the Mingw with GCC 4.7, because the Mingw with
GCC 4.6 works fine.

[I suspect Mingw with GCC 4.7 has been compiled with the frontend set to i686
but the backend set to i386. This causes substantial problems with any of the
i486 ops e.g. anything atomic or locking. Mingw does point out the GCC 4.7
build is beta.].

There is an argument in favour of deprecating Mingw completely in favour of
Mingw-w64, which is a ground up clean reimplementation.
