Also, although I am still getting this message:

You can get rid of that message by configuring with
--enable-force-reg. However, apart from the message this has no
effect on the PPC.
I use that flag, but it must no longer be turning off the message.
Right. Nowadays these performance options are tried out automatically
on platforms where they apply, so if you ask for it explicitly, that
is ignored.
I have now changed the Makefile to not report this stuff
automatically.
You can still get a report with
gforth --diag
gforth-fast --diag
I wonder how we should handle the case where there is no FORCE_REG
defined for the platform. Should we assume that this platform does
not need FORCE_REG (and not warn about it), or that the platform
support is lacking (and warn about it). For now I have added another
macro FORCE_REG_UNNECESSARY that suppresses the warning for PowerPC.
My choice is to not show warnings if the typical user can't fix them.
Repeated warnings just get ignored and there are way too many already
being generated by a gforth compile.
Thanks!
