What's the purpose of those macros then? Obviously, you cannot build the
same src.rpm for multiple distribution versions without editing it. If,
however, you used Ignacio's version, you could

  rpmbuild --define "fedora 4" --define "dist .fc4"

and build the same src.rpm for FC4. Exactly *that* was one of the
benefits of dist tags defined outside of the package and applied at
build-time.

If we need to edit the spec, we can as well do that in CVS prior to
commit.
