I'm glad to hear that as I had been suggesting that for quite a while.  The
include file for a particular processor should only contain the definitions
for that processor.  If you want compatibility from a 16 to and 18 PIC, then
you should make a separate include file for that (or Microchip could provide
it).

Keeping fluff out of a mandatory include file is just good design.  I don't
want undocumented symbols automatically created.  These will cause more
trouble in the long run than they are worth.  I would rather have the
assembler give me an error so that I can decide how to fix it.  I might want
to use a bunch of conversion symbols, but then again I may be specifically
looking for non-18 syntax.  Another problem is with conditional assembly
code that uses IFDEF to decide what to emit.  Such code may work other than
what the manual would lead you to believe when unexpected compatibility
symbols are defined.
