Hi Stepan,

Yes, which I agree is probably wrong, but at this time I want to allow
people to build ntp and not build sntp.  I may have to change my mind
on this one!

That will be Ugly, but I'll talk to Bruce about how we might do this.
If this is what we need to do, I suspect we'll have a 2nd argument to
the LIBOPTS_CHECK macro.

But this solution will only work if we *always* build sntp, as otherwise
sntp/libopts/Makefile will not be generated.  Again, this may be what I
have to do.

That's for Bruce to decide, I suspect.

You too, and thanks very much!
