Sorry, I didn't see it.  I don't think that patch is necessary.
Here are some more detailed comments:

As a rule, I don't think autoconf should be in the business of
defining new C functionality, as that intrudes on the programmer's
responsibility and namespace.  I think autoconf should define only C
symbols that tell you what works and what doesn't, and perhaps symbols
that replace non-working symbols.  Autoconf's job is hard enough as it
is; I'd rather not complicate everybody's lives by extending its scope.

This is merely a matter of English, but the old version seems more
correct to me, as "only" applies to "dummy", not to "have".
