Yes, I think you are missing something.  OS/390 doesn't need mmap_emul
since it has native mmap that works fine.  But AC_FUNC_MMAP tests for
MAP_FIXED which Apache doesn't use & OS/390 doesn't support.  So I
changed the mmap test to not use AC_FUNC_MMAP.

On the other hand, BeOS apparently needs mmap emulation, so the config
needed to be tweaked slightly to accommodate that.  David & I just
happened to hit the same piece of code at nearly the same time.
