For building perl to support Oracle, it needs to be linked with libcl
and libpthread. So even if your perl is an unthreaded build, these
libraries might be required. See "Oracle on HP-UX" below.
Beginning with HP-UX 11.00, programs compiled under HP-UX can take
advantage of the LP64 programming environment (LP64 means Longs and
-Pointers are 64 bits wide).

As of the date of this document, Perl is fully 64-bit compliant on
HP-UX 11.00 and up for both cc- and gcc builds. If you are about to
build a 64-bit perl with GNU gcc, please read the gcc section carefully.

In both cases, it is strongly recommended that you use these flags when
you run Configure. If you do not use do this, but later answer the
