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