<<Careful! "confused by earlier errors, bailing out" means that there
_was_ an ICE but we pretended it didn't happen because there was an
earlier error.  In this case, the undeclared strcmp and exit are
unlikely to have corrupted data structures down the line and provoked
the ICE, which means there's still a real bug here.  Put declarations
of strcmp and exit just above main() in that test file, and I bet you
the bug comes back.

This is why ICE suppression is a Bad Thing.

What we do in the equivalent case in Ada is to suppress by default, but have
a switch to unsuppress, and that has proved a useful compromise.
