Well, if you have access to the source, you can probably modify some constants to disable particular protocols, or there may be compile time options already - it would be nice to disable automatically on runtime if the host does not have a IPv6 protocol stack.
The system calls in question are:
getaddrinfo(3) http://www.kernel.org/doc/man-pages/online/pages/man3/getaddrinfo.3.html
or in older software:
gethostbyname(3) http://www.kernel.org/doc/man-pages/online/pages/man3/gethostbyname.3.html
My understanding was that AI_ADDRCONFIG does exactly that, only doing a given lookup if IPv6 is configured. If that's the case, then it's just woefully underused.
