Subject: [PATCH] [CRT] Fix _fmode

Remove mingw-w64 version of _fmode. _fmode should not be linked directly into the executable. Instead, the export from msvcrt should be used. On Windows 10 it's defined to *__p__fmode(), which is exported from ucrtbase.dll
Also _fmode in msvcrt.dll is initialized with 0.
