--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
a) and b) are the same.  I don't think c) is necessarily wrong code, but the
warning doesn't warn (and it shouldn't), so let's put that aside.  So this
boils down to

void
foo (int c)
{
  if (c ? 0 : 2)
    __builtin_abort ();
}

w.c: In function ‘foo’:
w.c:4:13: warning: ?: using integer constants in boolean context
[-Wint-in-bool-context]
   if (c ? 0 : 2)
       ~~~~~~^~~
