  I think NMU'ing at least the one-line fix, that is relevant for
building other software that uses libmng would be a good idea in
this situation. Not only for MPlayer, but all downstreams of linmng.

  If you think it won't be fixed soon in Debian, I can commit my
workaround patch defining MNG_NO_INCLUDE_JNG . We can revert that
part of the patch later when the issue is fixed in Debian.
