--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-02-27 17:18:41 UTC --- Probably not since the trunk is in stage4. This isn't a regression and mingw isn't a primary target. Someone with access to a mingw system would have to do it anyway, which as far as I know rules out all the libstdc++ maintainers.
