I confirmed Aaron's ext/dl can work with following
patched libffi on mswin32/VC9.
http://sourceware.org/ml/libffi-discuss/2010/msg00049.html

If this also works on mswin64 and libffi merge this,
we can reimport Aaron's new ext/dl.
Please try this who have other than mswin32/VC9 and feedback to libffi.
