--- Comment #4 from R. Diez <rdiezmail-gcc at yahoo dot de> --- That is certainly a way to fix the crt0 nuisance. But it requires some specs file black magic, so yet another thing to learn. And then you have to keep up with GCC in case something changes around the specs files. It is not a user-friendly solution.
