+=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.
+
+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.

 There are some drawbacks to this approach.  One is that any extension
 which calls any file-manipulating C function will need to be recompiled
