He is saying that when you do

    g++ nongpl.o gpl.o

you are creating a compilation, not a derivative work.

His other claim is that when you do

#include "gpl.hpp"
#include "nongpl.hpp"

int main()
{
    gpl( 5 );
    nongpl( 6 );
}

you are creating a compilation of gpl.hpp, nongpl.hpp and your own
copyrighted work, not a derivative work of gpl.hpp and nongpl.hpp.

Obviously if you _modify_ gpl.hpp or gpl.o, you are creating a derivative
work and the GPL applies in its full glory.

That's how I understand Alexander's posts.
