In particular, what I can't rule out without actual testing on Unisys
(which isn't available to me any more) is that, while -lnsl is more
fundamental than -lsocket on Solaris, it may be reversed on Unisys and the
test happened to work even though it was applying the libraries in the
wrong order.

Although the more I look at this, the more I think that Stepan is probably
right.
