GCC rejects this:
#ifdef defined
#endif

Even though C99 6.10.8.4 specifies that 'defined' is only disallowed after
#undef or #define.

------- Comment #1 from tromey at gcc dot gnu dot org  2006-12-28 01:28 -------
Also 6.10.8.4 says that various other macros, like __DATE__,
shall not be the subject of #define or #undef.  Currently we
warn in these cases but perhaps we ought to have a pedwarn instead.

I have a patch for the '#ifdef defined' case which I am testing.

Also I note that '#if defined defined' is undefined.
I wonder if we ought to warn for this.
