I believe that the official line, from upstream GCC, is that it is
unsupported, but you'll really need to confirm that with them.

My understanding is that it will not work with the windows thread model,
(which is what current MinGW-GCC is built to deploy.  It may be possible
to get it to work, if the compiler is built for the POSIX thread model,
but we don't do that ATM, and I'm not certain if it would be reliable if
we were to change that policy.
