ORBit buld problem on HPUX (with patch)

[Dan Newcombe <Newcombe mordor clayton edu>]

This is the same problem I've reported in the past where it fails to build
in connection.c.  Below is a patch that'll let ORBit build nicely on HPUX.
For more info on the problem, see the mailing list archives.

The problem file is src/IIOP/connection.c
