+-#       (With recent gcc, this is done with "-std=c89".  With older gcc, this
+-#       is done by passing "-lang-c89" to cpp, by passing "-Wp,-lang-c89" to

+-#       so much for compatibility!)
+-#
+-#       UPDATE: apparently there is NO WAY to tell gcc 3.2.2 to require that
+-#       declarations preceed statements, without resorting to "-pedantic".
+-#       This means that there is no way to get gcc3 to issue warnings that
+-#       ensure that your code complies with the ANSI/ISO C89 standard, without
+-#       also drowning in totally useless warnings.  Thank you master may I
+-#       have another.
+-#
+-#       So, I give up, let's just use -pedantic.

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

+-      #
+-      #   * On HPUX 9.x, where /usr/include/X11R5/ was standard, and
+-      #     /usr/contrib/X11R6/ could be installed as a patch, what was in
+-      #     that contrib directory?  Did it contain so-called "standard"
+-      #     X11R6, or did it include Xaw and Xmu as well?  If the former,
+-      #     where did one find Xaw and Xmu on 9.x R6 systems?  Would this
+-      #     be a situation where one had to reach into the R5 headers and

++      # "standard", notably, Xaw and Xmu, live in /usr/contrib/X11R6/.
++      # Yet /usr/contrib/X11R6/ comes preinstalled on all HPUX systems.
++      # Also, there are symlinks from /usr/include/ and /usr/lib/ into
++      # /usr/{include,lib}/X11R6/, so that (if you don't use Xmu at all)
++      # you don't need any -I or -L arguments.
++      #
++      # On HPUX 9.x, /usr/{include,lib}/X11R5/ and /usr/contrib/X11R5/
++      # are the same division as 10.x.  However, there are no symlinks to
++      # the X stuff from /usr/include/ and /usr/lib/, so -I and -L
++      # arguments are always necessary.
++      #
++      # However, X11R6 was available on HPUX 9.x as a patch: if that
++      # patch was installed, then all of X11R6 went in to
++      # /usr/contrib/X11R6/ (there was no /usr/{include,lib}/X11R6/.)
++      #
++      # HPUX 8.x was the same as 9.x, but was X11R4 instead (I don't know
++      # whether R5 was available as a patch; R6 undoubtedly was not.)

++      # that are available.  We do not mix and match different versions

++      #
++      # Question I still don't know the answer to: (do you?)
++      #
++      #   * On HPUX 9.x, where /usr/include/X11R5/ was standard, and
++      #     /usr/contrib/X11R6/ could be installed as a patch, what was in
++      #     that contrib directory?  Did it contain so-called "standard"
++      #     X11R6, or did it include Xaw and Xmu as well?  If the former,
++      #     where did one find Xaw and Xmu on 9.x R6 systems?  Would this
++      #     be a situation where one had to reach into the R5 headers and
++      #     libs to find Xmu?  That is, must both R6 and R5 directories
++      #     be on the -I and -L lists in that case?
