For example, if I'm developing a program, I'd like to be able to build a
version of it based on what I've just checked in, which likely won't
have a defined version number.  I'm going to be building working (or
non-working) versions of the program much more often than I'm going to
be doing "official" releases.

One alternative is to define a new version number for each commit.  vim
does this; the latest version in its git repo is v8.1.1446.  But if you
don't want to do that, a version that includes the date and (part of)
the git commit hash also works, and uniquely identifies the version of
the source from which it was built.
