453 # The following arcana was gleaned from conversations with

456 # On HPUX 10.x, the parts of X that HP considers "standard" live in
457 # /usr/{include,lib}/X11R6/. The parts that HP doesn't consider
458 # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
459 # Also, there are symlinks from /usr/include/ and /usr/lib/ into
460 # /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
461 # you don't need any -I or -L arguments.
463 # On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
464 # are the same division as 10.x. However, there are no symlinks to
465 # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
466 # arguments are always necessary.
468 # However, X11R6 was available on HPUX 9.x as a patch: if that
469 # patch was installed, then all of X11R6 went in to
470 # /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
472 # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
473 # whether R5 was available as a patch; R6 undoubtedly was not.)
475 # So. We try and use the highest numbered pair of
476 # /usr/{include,lib}/X11R?/ and /usr/contrib/X11R?/{include,lib}/
477 # that are available. We do not mix and match different versions

482 # * Does HPUX 10.x come with /usr/contrib/X11R6/ standard?
