The problem is that you are using the standard cc included with HPUX. Unfortunately, that compiler is just about sufficient to relink the kernel, and that's it. No fancy tricks and certainly no ANSI C, which is what this module's C code is using. You need to use a compiler that understands ANSI C by doing setting the CC environment variable before doing anything.

To get such a beast on HPUX, you could either use HP's Ansi compiler, which, if installed on your system, should reside in /opt/ansic or /opt/aC++. You could also install gcc on your system. You can get gcc at the HPUX software porting centre or through HP's website (search for gcc). If you will be using gcc on HPUX 11.x, be sure to get HP's version, as the unpatched open source version barfs on some of HP's include files. Also do not forget to install GNU binutils as well if you install gcc, you'll get interesting results otherwise.
