I have a patch for the reported issue, but gcc actually has
many special defines...

/* Different flavors of builtin macro.  _Pragma is an operator, but we
   handle it with the builtin code for efficiency reasons.  */
enum cpp_builtin_type
{
  BT_SPECLINE = 0,        /* `__LINE__' */
  BT_DATE,            /* `__DATE__' */
  BT_FILE,            /* `__FILE__' */
  BT_BASE_FILE,            /* `__BASE_FILE__' */
  BT_INCLUDE_LEVEL,        /* `__INCLUDE_LEVEL__' */
  BT_TIME,            /* `__TIME__' */
  BT_STDC,            /* `__STDC__' */
  BT_PRAGMA,            /* `_Pragma' operator */
  BT_TIMESTAMP,            /* `__TIMESTAMP__' */
  BT_COUNTER,            /* `__COUNTER__' */
  BT_FIRST_USER,        /* User defined builtin macros.  */
  BT_LAST_USER = BT_FIRST_USER + 31
};

I didn't try to handle them all.
