Update to a newer version of gcc.  Newer versions are much better about 
handling
out of range branches/calls.

But I bet you're not using it on the line to create the shared library.
Creation of a shared library also involves compiling code on some targets
(such as the PA).  You need to ensure that code is PIC too.

-mshared-libs/-mno-shared-libs were very very old options and are no longer
necessary.  gcc has been able to correctly produce shared libraries on hpux for
about 6 years now.
