Please find attached a patch that works around some problems compiling NRPE on HP-UX. Note that I was able to compile NRPE with full support for SSL & command arguments. Unfortunately, we're only running HP-UX 11i v3 PA-RISC, so I'm unable to test this on IA64 or other HP-UX versions. Also, I'm sure there is a cleaner way to skip the TCP wrapper (HAVE_LIBWRAP) sections within configure too, but I'm not familiar enough with autoconf & don't really have the time. Knock yourself out.
