  But there isn't much we can do about this, this means the libc interfaces
are not standardized on Windows.

  Maybe one thing we can try do is minimize the reliance on FILE * . I would
hope fd integers values might be more portable across implementations
(or at least not lead to crashes). Of course we can't just deprecate FILE *
based APIs but making sure we don't use them too much internally and maybe
document the associated problems. I think most of the FILE based APIs are
about dump or debug output, and with the xmlSave module it should be as
convenient to use Fds .
  For internal use it's maybe the xmlIO.c which could be cleaned up 
a bit, but it's unclear this would really bring much benefits.
