What problem?  Fix the sources if tcc complains.

As removal of the message introduces a quality of implementation 
regression without improving anything, yes, reverting it is actually the 
solution.

Why?

It's not GCC that complains, it's GNU ld.  And no, tcc is fully right to 
complain here, it's incorrect C to have two definitions, so tcc is 
actually better than GCC+GNU ld in their default mode on recent 
architecture+os combinations in diagnosing it.

None of this.  The error message is correct.
