I would like to change the values of VALBITS and GCTYPEBITS (from the
defaults of 24 and 7, to 26 and 5).  But I notice that dependences on the
values 24 and 7 are hard coded in at least two places:

1) In lisp.h in the definition of the Lisp_Object union, and

2) in m-<some machines>.h in the definition of SIGN_EXTEND_CHAR
    (m-ibmrs6000.h, for example).


Question:  Should these dependences be be replaced by uses of VALBITS or
GCTYPEBITS (as I suspect) or am I wrong in my assumption?

Note that this is important for more than just those of us trying to sqeeze
more capacity out of Epoch/Emacs, since some m-*.h redefine VALBITS and
GCTYPEBITS for good reasons.

Also, please let me know if this should be directed at the Emacs list
instead.

Thanks,

- Jim
