It won't help with your auto-bootstrap I suspect, because I expect that
is scanning for certain hard-coded macro names to detect recursion, and
it won't know about my macro (because it re-implements rather than
wrapping, there is nothing to catch the recursion).

This is likely to cause problems with some of the other "auto" features
as well - I expect it to break the --help=recursive option to configure,
but that's broken already for Audacity, so I didn't test.
