    Use multi-byte codepage aware string function on Windows
    
    The East Asian double-byte codepages have characters with backslash as
    the second byte, so we must use _mbsrchr() instead of strrchr() when
    looking at pathnames in the system codepage.

    Fix heap corruption on Windows in FcEndElement()
    
    Must not call FcStrFree() on a value returned by
    FcStrBufDoneStatic(). In the Windows code don't bother with dynamic
    allocation, just use a local buffer.

    Fix MinGW compilation
    
    Need to define _WIN32_WINNT as 0x0500 to get declaration for
    GetSystemWindowsDirectory().
