Oops, I hadn't looked at all the #defines carefully before I sent this.
I was mistaken; there is no problem.

------------------------------- Referenced Note ---------------------------
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
