Thanks for explaining that.  I misunderstood something you said in
your previous email about libuca being a system library; I thought you
meant by that that the compiler linked it automatically on HP-UX,
without needing "-luca" in the invocation.

(I actually included this change in what I committed yesterday, so no
further change is needed now.)
