There's a difference between a program compiled without thread support
and a program compiled with thread support that only uses one thread.

If NetBSD isn't following standards it should be fixed.   But, in 2012 a
program that can't run in a threaded environment seems broken.   I would
suggest looking at the GNUMail sources to figure out what it's doing
with _res and if it's easily avoidable.

Alternatively, you can build it without thread support, but that may
required building lots of prereqs without thread support also.
