If I understand the supporting documents to the GPL, I think you are
mistaken. The GPL defines a derived work as within the same process space,
so, RMS by defining "derived work" within the context of GPL has also
extended what the GPL is intended to cover. Static or dynamic linking
doesn't make a difference, the code is intimately linked when the program
is run.

The only way to avoid touching GPL is a call gate or TCP/IP type
mechanism. That's why all libraries should be LGPL.
