Hi Esa -
Thanks for reminding me about the distinction between source and object 
files. I keep forgetting that object files exist (!) and that it's 
sufficient for LGPL to just make them available.

Still, a slight problem is that since there is one object file per source 
file, the names of the object files give quite a lot of information away 
about the structure of the program especially when they are arranged in a 
module hierarchy, so I'll be glad when GMP is replaced by something without 
such a burdensome licence. (Although perhaps I can bundle my object files 
into a single library file but I don't know how to do this yet, or if it 
would really help in the goal to make the code completely obfuscated, 
impenetrable, and unavailable to any rival company... ;-) )

Thanks again,
Brian.
