"Derivative Work" for Software Defined

[Lawrence E. Rosen]

I continue to believe that these confusing messages about "derivative
works" entirely miss the mark.  Where in the statutory or case law can
one find support for such conclusions as are reflected in these
messages? 

If you don't create "a work based upon one or more preexisting works"
then you have simply not created a derivative work.  17 U.S.C. §101.
How in the world does an independently-written piece of software that
communicates with another independently-written piece of software
through a published API ever become a derivative work of that other
software?  Where in the GPL does it say that it can become a derivative
work?  

Nothing in the Copyright Act addresses the *use* of software in this
way.  If the GPL is enforced under the copyright law, then how could a
court ever conclude that it reaches to such API-connected pre-existing
works that merely get used together?

If all one is using are headers or .h files and everything else is from
scratch, does using the headers under the statement above comply with
the intent?

I am not seeking an opinion without paying for it.

In what way would a restrict cut both ways here?

I am a little naive, but always try to do the right thing.
