A nicer way to do this I think would be to use an std::unique_ptr to hold the freshly-allocated Function object until its ownership can be transferred to the PrescribedMotion constraint. It would look something like this:

std::unique_ptr<Function> func(new Function()); // func has ownership
ReferencePtr<Function> funcref(func.get()); // keep a reference to Function object
Constraint::PrescribedMotion(func.release()); // take over ownership from func

OK, I did. Please review.

Hmm. AppVeyor build died immediately; related to this morning's AppVeyor update? Chris, please see separate email.

Added a commit to allow "deprecated-declaration" warnings to occur without error until we fix issue #528.

I'm merging this now because it fixes the CI builds.

Okay; @aseth1 definitely should look at these changes at some point.

Thanks for doing this @sherm1 .
