I agree that "5.91" is the right alpha-version string, assuming that
it's intended as an "alpha" in the sense of our release rules (as
opposed to a "release candidate", which has a non-zero W).


The problem with the release branch currently is that "5.91.0.0" is
not a valid version string, and so

 #define MZSCHEME_VERSION "5.91.0.0"

creates trouble, right?
