I've made my own templates that include both our companys copyright notice 
and a skeleton for a new class. I delete the empty class that is generated 
by "New class" and substitute the correct name and set the correct 
namespace into my own skeleton, so this doesn't apply to me in any case. 

It's hard to draw the line her though. I've written elisp functions for
emacs that inserts class templates. If functions like these were supplied
with emacs, and I used them to create empty classes, would that make the
empty classes derived work?

This becomes a bit different, as there is actual code generation here.  
When creating a class in KDevelop, I supply the name for the class, which
really means that I created all the code except parentheses and braces.
There is no generated code which does not originate from my selection of a 
name for the class (ctors and dtors contain no code) which leads me 
to think I'm only deriving from my own work.

In KDevelops case it just boils down to nitty-gritty for the lawyers like 
"is an empty constructor generated code or not". I believe it would never 
hold up in court. Bison however, actually generates code.

My $0.02 :)
