It could be that the best way to get rid of some of these warnings
is to delete some -W option that causes GCC to issue them.

In the case of _Noreturn, isn't there a simpler approach,
defining a macro that expands into either _Noreturn or nothing?
Or defining _Noreturn as a no-op when there is no other definition?

Surely it is easier to put in some code that will
unconditionally use that variable.  But maybe just delete
the -W option that causes these warnings.

To clutter up the code to placate a finicky compiler is a change
for the worse.  If the compiler is so finicky only because a special
option asked it to be, why be massochistic?
