Digging a little further ... The conflicting dll was /bin/cygpng16-16.dll.
rebase display it with a * indicating that there was a space conflict for it. So I did a rebase-trigger full and ran setup again. Now these two dlls share the same spot: /usr/bin/cygp11-kit-0.dll /usr/lib/p11-kit-proxy.so ... but that seems to be because one is a link to the other. I'll see how things go. I had thought that doing rebase-trigger full and rebasing was no longer necessary, but maybe things somehow got messed up so that the automated mechanism failed for me ... We'll see if I am back to no vfork errors.
