Oh dear, it misses a break indeed. I don't remember the exact test I did but 
that was a home made assembly file with no code so I couldn't test the output. 
I did however checked the result of the relocation and I remember the 
relocation gave a different result on gcc and tcc but that is expected because 
the symbol doesn't end up at the same adress in the final executable. So I 
tried to compare the computation done in both case and compare with this 
formula. Obviously I failed somewhere.

I'll add this break but before committing I'll try to create a full program 
which I will be able to execute. Good you noticed.

Are you sure you're still ok with "master permission"? ;-)

I've just created an account robotux on repo.or.cz.

Best regards,
