Section 4.1.2 of (my draft of) the ANSI standard states that "All external 
identifiers that begin with an underscore and iether an upper-case letter
or another underscore are reserved."  However, this simply means that these
identifiers may be defined in standard header files, so the user should not use 
these names.  The standard does NOT say that the implementor may use these 
identifiers to change the syntax of the C language, as you are doing when you
introduce things like "__chip".

I'm sorry, but I can't find this in the standard.  Can you direct me to 
the appropriate paragraph?  Or perhaps this is something from the "Rationale"?

Again, I think that you guys are missing the point.  It seems to me that the
ANSI committee provided #pragma  exactly for handling non-standard things,
such as "__chip", which can't otherwise be done in the language.
