I haven't done HP in a while, but isn't there supposed to be an -fPIC
option when compiling code that's going into shared libraries?  Check
the "Creating an Ada Library" section of the GNAT User Guide.  (I would,
though, drop the -O0 option since there's no benefit to doing that, and
-gnatf and -gnatwu have no effect on the generated code.)
