--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Rainer Emrich from comment #4) > Revison 232071 broke bootstrap on x86_64-w64-mingw32, see bug 69440. > I can't test until trunk bootstraps again for x86_64-w64-mingw32. You could manually revert that commit in the latest trunk and retry.
