  Oops.  I thought I did the cvs add for that file a long time ago, but I=

didn't.  It's there now.

  I think so, although I'm not sure if they are in there yet.  Is that th=
e=20
way it is normally done?

  Yes.  I'm not sure if this is implimented yet, but the idea was that th=
e=20
compiler would check for the largest used type, and create the MATHx=20
registers this size.  Right now it may just be #define'd somewhere.

  I think the current code uses the hardware stack (for the PIC instructi=
on=20
set).  With the AVRs, it looks like a real stack (no hardware limits) wil=
l be=20
possible.  I would like this to be configurable, but it isn't yet.
  I think right now function return values are always in MATHB.  MATHB is=
=20
kind of the central point for all memory movement. =20

  I'll be looking at gra1.y and gra_util.c next, since that is where the =
work=20
to be done is.
