[Fedora-legal-list] modified MIT license in GPLv3+ source

[Christian Krause]

Hi,

I'm currently packaging the tool "pianobooster":
https://bugzilla.redhat.com/show_bug.cgi?id=494965 and I've discovered
the following problem:

The source (GPLv3+) contains 3 files ("rtmidi/*") which are licensed
under a modified MIT license. In general this should be ok, but this
license contains the statement that modifications must be sent back to
the author. For the full license text from the source files see below.

I've set the FE-LEGAL block for the review request (BZ #494965)

Please can the legal team have a look at the problem (and hopefully
remove the FE-LEGAL block)? ;-)

If there's no problem, what would be the correct License tag in the spec
file? GPLv3+ and MIT?

Thanks!


Best regards,
Christian
