Hi.  Here's the latest list of predefined CPP symbols (at least, the
ones I know of).  These are generally used to allow machine and/or
operating system specific code to be #ifdef'ed.  Very few of these are
actually documented anywhere; the purpose of this list is to try to
take some of the "folklore" and make the information available to
everyone.  The data here is collected from a number of sources; please
see the "acknowledgements" list at the end of this article (if you sent
me something and don't see your name listed, better send it again).  I
don't have any data on anything earlier than V7.
