[PD] porting a Pd patch to Max license issues

[Marco Donnarumma]

thanks for the hint Bryan,
that might apply.
In this case, porting the code to Max or Max4Live is not legal, unless I
specify an additional exception for it, is it correct?

so now, to make it spicier,
I found this FAQ:
~~~~~~~~~~~~~~~~~
If a library is released under the GPL (not the LGPL), does that mean that
any software which uses it has to be under the GPL or a GPL-compatible
license?

Yes, because the software as it is actually run includes the library.
~~~~~~~~~~~~~~~~~

is this a show-stopper for porting of the XS into a proprietary environment?
