No license is incompatible with new BSD by definition. BSD does not
require any sort of compatibility.

And you are not required to do so, to distribute a derived work under
the terms of the GPL. The GPL does not require you to change the
license, only that every part of the program has a compatible license.

Nobody ask you to do so, and nobody can under the law anyway (except the

That was the former BSD license, not the new one, and GPL requires too
that copyright holders need to be listed.

That's an author problem, as he choose a license that can be
incorporated in totally non free programs.

If the programmer really do not want freedom be taken off, than he
really should choose GPL.

True (for the new BSD).
