Are you saying that there is no way to remove presumably dead code
from gcc?

I didn't propose to mark all code not executed in the testsuite, only
lines where nobody can figure out why they ever would have been used.

Hmm. I'm mainly talking about the C++ front end. The number of system
calls there is rather low.
