A buildbot got angry about this new test, with error messages like:
warn-nullchar-nullptr.c Line 16: use of undeclared identifier 'u'
It looks like this `u'c'` syntax was introduced in C11; I'm guessing
some bots may default to something before that. Let's see if explicitly
specifying the standard version makes it happy...

This patch adds a warning that diagnoses comparisons of pointers to
'\0'. This is often indicative of a bug (e.g. the user might've
forgotten to dereference the pointer).
