That was how I originally wrote the code - the weak/mismatch case was added
by David Dawes in the XFree86 integration because he was seeing crashes on
FreeBSD when the server was built with IPv6 support but libc was not
(possibly because they were linked, statically or dynamically, with an older
 version of libc, but somehow also linked with a new version of libX11):

Presumably, that case is far more rare in 2009 than it was in 2003, and I
have no objections to not catering for it.   Certainly it's not something
that we'd support on Solaris/OpenSolaris - I don't know about other OS'es.
