Subject: PATCH: xntp3-5.87 configure.in

David,

	configure should only add -lsocket and -lnsl for systems
which require it.  Adding it on 5.x IRIX systems can cause problems.
Patch follows.

	There's one other item which I don't have a patch for at the
moment, but wanted to pass on.  The install target uses bin.  Since
these programs are administrative and usually require root, it seems
appropriate to use sbin, instead.

			yours,
