I did two things:
- I reverted my changes from the upcoming release branch. I don't want to
risk to break anything there. As it turns out, even small changes may have
significant impact...
- The CVS::HEAD branch now contains a fixed version correctly implementing
the functionality you have been asking for. The problem was, that the
is_defined_macro function you were using was not designed to take string
iterators, it is designed to take a token sequence as its parameters. But I
added a separate function for your convenience taking just the string
parameter as described in the docs.

HTH
Regards Hartmut

PS: note that the changes I committed to the CVS::HEAD may take some time to
show up in the anonymous checkout.
