This is a long story, but the short version is that the above is not an
error, and is required to have pmemd.cuda in Amber18 work correctly.

"sm70flags='-gencode arch=compute_70,code=sm_70'" is what we have
in the development version for the Amber20 release, but that requires
code changes that have not been backported (yet?) to Amber18.
(I don't know anything about sm_72 and sm_75).

Amber (even in the development version) doesn't seem to be doing this,
and I haven't noticed problems. But maybe this will bite us soon: I'll
keep my eyes open.
Thanks for the reports!....dac
