Midpoint is a flag in cntrl however to toggle between dpfp and spdp we need a compile switch.

Ahh...I didn't know that...probably explains why cmake is doing the same
thing....cc-ing to Jamie Smith, with apologies for not knowing this.

Also info for Jamie. My current plan is to at least remove those
chapters from the manual. (This is our standard deprecation strategy:
first remove things from the manual, but leave in the code; people that
really need it can get instructions from previous manuals.)
NOTE: anyone who thinks this deprecation is a bad idea needs to speak up
ASAP! But also note: we can always un-do this change with a future
update if unintended consequences show up.
In this case, we might also disable builds, since we can't test them.

I figured that. But note that there is no plan '-midpoint' option in
the current (legacy) configure script. Is midpoint somehow now a
default?
...thx...dac
