Exactly.  The extensions are bool, true, and false.  But the file
uses _Bool to define bool, which does not exist.  The user is not
allowed to define _Bool for himself, because it is in the wrong
name space.

You may have noticed that the substitute file I use for my own
purposes defines bool as int, thus avoiding the problem.
