"ugh".

I think this is a fallout from the __NetBSD_Version__ change in 2.1,
because firefox/mozilla/thunderbird test __NetBSD_Version__ and use
thread-safe resolver functions if it's recent enough.

my guess is that the change in NetBSD 2.1 means this code is turned on
in Firefox, but I think 2.1 lacks the thread-safe resolver functions,
so it breaks.

look at patches/* and see if you can tweak the version number to do
the right thing..

grant.
