I wrote the attached macro to solve a closely related problem (looking for ntohl, not getaddrinfo; the way Winsock works, it's equivalent). Perhaps it will be useful to you. Going forward I think AC_*_FUNC[S] really need to grow a way to specify headers. Fake-declaring everything as "char foo();" has been kinda silly for years now. zw
