I'm certainly no lawyer, and could be completely mistaken.  But I
believe that distributing such code under the GPL does not violate any
of these conditions.  All notices and disclaimers can remain in place,
the copyright remains intact with the author, who in any case is free
to separately distribute the code the way they see fit.  But if one
receives the code from someone distributing it under the GPL, then
said person has the *added* restriction that any binaries they
distribute must be accompanied by the source.  Just my understanding,
of course.  The distribution of binary maxima compiled with CMUCL is a
good example.

Take care,
