I've been meaning to post this patch for consideration for several years.  It is
non-intrusive, with no impact on other architectures, simply adding support for
loading of dynamic libraries on IA64 and HPPA HPUX 11.00 and newer.

While HPUX 11.31 has finally introduced dlopen() support, those calls are not
available to production machines with older releases of the OS installed, and in
any case, the official APIs are still the usual way to open library objects even
on 11.31 where the dlopen() compatibility wrappers are provided.

In case the patch does not make it in to the official release, at least this post
makes it available in the list archives for other HPUX users to discover.

Cheers,
