I'm adding a commment here to document a change related to commment 24 that I
just checked in as revision 325836 for bug 4619 in case a problem leads back to
this bug report.

That change contains a different fix for this bug's comment 24 that does not
require using the AF_INET6 macro and therefore doesn't neeed the various tests
for AF_INET6 being defined. The problem brought up in comment 24 is that on some
platforms creating a socket using AF_UNSPEC doesn't work if the source and
destination addresses are in different domains, with the symptom being an EINVAL
error on the send. Instead of replacing AF_UNSPEC with AF_INET6 or AF_INET, as
was done here, the new fix replaces the LocalAddr with "::" or "0.0.0.0" to
match the PeerAddr family.
