Charles would be the one to thank for most of the fixes (to Clang and
Wine). Henri Verbeet and Ricardo Filipe sent quite a few patches as
well. All of them can be found here:


For its current status, my test scripts builds wine daily with gcc and
clang and submits test results. You can compare them here (for today's
