It should warn because for everything except the very special libgcc_s vs. 
glibc case the user is warned about a real problem. In the normal case if a 
symbol is moved, you simply reversion it and want to be warned if you forget 
that. 

Contrary to your patch, I would rather strengthen the warning, cause it really 
should warn too if both symbols are default non-weak symbols with the same 
version, not warning about that caused the libgcc_s vs. glibc mess in the 
first place.

Franz.
