That's good to know, nice that it should be consistent and give a good
description of the check.

No problem, it is tricky to try the configure step with different
versions. I just did a new build off of master and I ended up with an
Emacs linked to libmagick version 7 and it opened images just fine.
Seems like everything is working.

Thanks again for your help getting this in.
