You need exceptions (so e.g. C++), and then GCC will force you to
use either -shared-libgcc or -static-libgcc to link, otherwise things do not
work.

I believe this was discussed in the past, and that people ended up saying
"that's the way it is, because of backward compatibility, etc...", so
we basically had little choice but to patch this in gnatlink.
