Sorry for my late response; yesterday I touched the laptop again, and 
saw your message after googling.

I'll instead show the tcc compiled tcc version;

I'll try to compile gdb; but I have another observation. It does not 
seem that tcc creates broken object files. For example I can compile 
something to .o when linked using gcc I end up with a working binary.
