recent version of the Perl distribution, these flags are set automatically.
+=head2 The GNU C Compiler
+
+When you are going to use the GNU C compiler (gcc), and you don't have
+gcc yet, you can either build it yourself from the sources (available
+from e.g. http://www.gnu.ai.mit.edu/software/gcc/releases.html) or fetch
+a prebuilt binary from the HP porting center. There are two places where
+gcc prebuilds can be fetched the first and best (for HP-UX 11 only) is
+http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,547,00.html
+the second is http://hpux.cs.utah.edu/hppd/hpux/Gnu/ where you can also
+find the GNU binutils package. (Browse through the list, because there
+are often multiple versions of the same package available).
+
+Building a 64bit capable gcc from source is possible only when you have
+the HP C-ANSI C compiler available, which you should use anyway when
+building perl.

=head2 Using Large Files with Perl on HP-UX
Beginning with HP-UX version 10.20, files larger than 2GB (2^31 bytes)
compiled using structures and functions in which these are 64 bits wide,
rather than 32 bits wide. (Note that this will only work with HP's ANSI
C compiler. If you want to compile Perl using gcc, you will have to get
-a version of the compiler that support 64-bit operations.)
+a version of the compiler that support 64-bit operations. See above for
+where to find it.)
There are some drawbacks to this approach. One is that any extension
which calls any file-manipulating C function will need to be recompiled
compiler. If you want to compile Perl using gcc, you will have to get a
version of the compiler that support 64-bit operations.)
+=head2 Oracle on HP-UX
+
+Using perl to connect to Oracle databases through DBI and DBD::Oracle
+has caused a lot of people many headaches. Read README.hpux in the
+DBD::Oracle for much more information. The reason to mention it here
+is that Oracle requires a perl built with libcl and libpthread, the
+latter even when perl is build without threads. Building perl using
+all defaults, but still enabling to build DBD::Oracle later on can be
+achieved using
+
+ Configure -A prepend:libswanted='cl pthread ' ...
+
+Do not forget the space before the trailing quote.
+
+Also note that this does not (yet) work with all configurations,
+it is known to fail with 64bit versions of GCC.
