Hello.

I'm having trouble understanding your point(s).

* C89 doesn't define _Bool.
* Does C90 define _Bool? What is C90?
* C99 does define _Bool.

The C99 sections are protected by:

     (Standard C version defines >= C99) && !(strict ANSI)

If we're using -ansi/-std=c89/-std=gnu89, __STRICT_ANSI__ will be 
defined but the C version defines won't. So the C99 section will *not* 
be included.

If we're using -std=c99/-std=gnu99, then __STRICT_ANSI__ and the C 
version defines are defined. So the C99 section will be included.

If no -ansi/-std switches are used, then __STRICT_ANSI__ is not defined 
and the C99 section will be included. Note that this is independent of 
whatever mode the compiler operates in by default.

So I don't see what the problem is.

Thanks, bye, Rich =]
