The patch doesn't seem right to me: it is removing a symbol marked as DATA, therefore the mingw-w64-compiled code should have this symbol imported from msvcrt.dll but do so from libmingwex. The only way this symbol goes into mingw-compiled code is that it has a foreign symbol compiled by e.g. msvc?
