Maybe we can abandon Mac OS X 10.2 in 8.3 and later? And not back-
port these patches to the 7.x, 8.0, and 8.1 branches?

BTW, I think the configure probe (only on Darwin, correct?) should
test for the existence of <dlfcn.h>.

The Bonjour patch wasn't intended to be portable to other platforms
just yet. As submitted, it has the same risks/advantages as this
dlopen() patch -- it only works on 10.3 and later, but isn't
deprecated in 10.4.

If we want to keep 10.2 support for Bonjour, we can test for both
DNSServiceDiscovery.h and dns_sd.h in ./configure, and prefer
dns_sd.h if it's found (which will be the case for 10.3 and 10.4) but
use DNSServiceDiscovery.h if not (which will be the case for 10.2).

Thanks!
