We have a case here of a work composed of two parts:

A) a gpl'd library
B) a main program with a gpl-incompatible license

The combined act of distributing A and B, with the intention to
combine them into A+B is the combined case.

Distributing A alone is not illegal.  Distributing B alone is not

Distributing A+B is illegal.  And it's illegal no matter how many
people divide up the work, as long as what they are doing is intending
to distribute A+B.  You have to look at the *total situation* and not
just ask "is linking a copyright violation"?

The case we were talking about *is* a relevant example.
