    Bug 660730: Win32: Only use _fstat32 if available
    
    _fstat32 is only introduced with msvcrt80.dll (i.e. Visual C++ 2005),
    in which using this function will break compilation with MinGW,
    which links against msvcrt.dll.  The msvcrt.lib in the Windows DDK
    which links to a later incarnation of the msvcrt.dll in later Windows
    systems may have this symbol defined, but that needs to be checked
    upon to be sure.
    
    Thanks to Dieter Verfaillie for pointing out this problem.
