86:  How do I build Emacs under HP-UX 8.0?
  
  Problems fixed in 18.58: missing errnet.h, `Cannot do arithmetic with
  pointers to objects of unknown size' (void *), not finding -lX11, unexec
  making a bad dumped emacs due to shared libraries (`Fatal Error(11)-
  Segmentation Fault', I think).
  
  If libX11.a is missing, you may need to run `update' again to load the
  X11-PRG `fileset'.  This may be missing even if you specified `all
  filesets' the first time.  If libcurses.a is missing, you may need to load
  the `Berkeley Development Option' {???}.  You can always define
  CANNOT_DUMP and link with the shared libraries instead.
