820 # /usr/{include,lib}/X11R6/. The parts that HP doesn't consider
821 # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
822 # Yet /usr/contrib/X11R6/ comes preinstalled on all HPUX systems.
823 # Also, there are symlinks from /usr/include/ and /usr/lib/ into
824 # /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
825 # you don't need any -I or -L arguments.
827 # On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
828 # are the same division as 10.x. However, there are no symlinks to
829 # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
830 # arguments are always necessary.
832 # However, X11R6 was available on HPUX 9.x as a patch: if that
833 # patch was installed, then all of X11R6 went in to
834 # /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
836 # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
837 # whether R5 was available as a patch; R6 undoubtedly was not.)
839 # So. We try and use the highest numbered pair of
840 # /usr/{include,lib}/X11R?/ and /usr/contrib/X11R?/{include,lib}/
841 # that are available. We do not mix and match different versions
844 # Question I still don't know the answer to: (do you?)
846 # * On HPUX 9.x, where /usr/include/X11R5/ was standard, and
847 # /usr/contrib/X11R6/ could be installed as a patch, what was in
848 # that contrib directory? Did it contain so-called "standard"
849 # X11R6, or did it include Xaw and Xmu as well? If the former,
850 # where did one find Xaw and Xmu on 9.x R6 systems? Would this
