OK, I'm convinced.  I've changed unistd.h to use 0xC0000404 (on the next
page) for the syscall gateway, although we can easily change it back.

The ``Assembly Language Reference Manual'' I have says:
  Refer to the /HP-UX Reference/ manual for more information on HP-UX
system
  calls.

Anyone know what manual they're talking about?  I'd like to find out
what to do for syscalls that take more than 4 arguments, like mmap and
recvfrom and sendto.
