Unfortunately, the autoconf tests appear to all not quite do what we
want - then we end up copying and rewriting them.  I'd be willing to
incorporate an improved MMAP macro into configure.in, if you'd like to 
contribute one.  Or add an explicit test for HP-UX, and only use
AC_FUNC_MMAP only on non-hp-ux systems.
