This isn't funny.  If it's currently not a problem, but can be, the
license is non-free.

I'm talking about "compilation" in the sense of "combine two or more
works into one", not in the sense of "running a compiler" or any other
sense it possibly has.  And I don't see how a patch clause forbids
this.  In the simplest case, the second work is arranged to be a patch
of the first.  If I want to combine two such works, and apply changes,
it's getting technically burdensome, but only until someone has written
cdps (common Debian patch{clause} system).  This is different with
invariant sections and the problems they cause when creating combined
works or stripped-down works, since they cannot be solved technically.
