Could you please tell me the versions of gcc, binutils and glibc?

No.

And if it is defined?
There will be a the same conflict with libgcc2.a
I'm affraid it's not a solution.

I believe it should not be a problem.

Maybe.

Who knows. You may have exactly the same functions and a very forgiving
linker.

It helps, but I don't think it's a solution.

I'm not so pessimistic.
