   Emacs 20 may work on HPUX 10.  You need patch PHSS_6202 to install
   the Xaw and Xmu libraries.  On HPUX 10.20 you may need to compile with GCC;
   when Emacs was compiled with HP's C compiler, HP92453-01 A.10.32.03,
   the subprocess features failed to work.
 
-  19.26 is believed to work on HPUX 9 provided you compile with GCC.
-  As of version 19.16, Emacs was reported to build (using GCC) and run
-  on HP 9000/700 series machines running HP/UX versions 8.07 and 9.01.
-  The HP compiler is known to fail on some versions if you use +O3,
-  but it may work with lower optimization levels.
-
-  Use hppa1.1-hp-hpux9shr to use shared libraries on HPUX version 9.
-  You may need to create the X libraries libXaw.a and libXmu.a from
-  the MIT X distribute, and you may need to edit src/Makefile's
-  definition of LIBXT to look like this:
-
-     LIBXT= $(LIBW) -lXmu -lXt $(LIBXTR6) -lXext
-
-  Some people report trouble using the GNU memory allocator under
-  HP/UX version 9.  The problems often manifest as lots of ^@'s in the
-  buffer.
-
-  We are told that these problems go away if you obtain the latest
-  patches for the HP/UX C compiler.  James J Dempsey
-  <address@hidden> says that this set of versions works for him:
-    /bin/cc:
-           HP92453-01 A.09.28 HP C Compiler

-            Ucode Code Generator - HP-UX.09.00.23.5 (patch)  2/18/93
-
-  For 700 series machines, the HP-UX patch needed is known as
-  PHSS_2653.  (Perhaps for 800 series machines as well; we don't
-  know.)  If you are on the Internet, you should be able to obtain
-  this patch by using telnet to access the machine
-  support.mayfield.hp.com and logging in as "hpslreg" and following
-  the instructions there.  Or you may be able to use this
-  web site:
-
-    HP Patch Server: http://support.mayfield.hp.com/patches/html/patches.html
-    HP Support Line: http://support.mayfield.hp.com
-
-  Please do not ask FSF for further support on this.  If you have any
-  trouble obtaining the patch, contact HP Software Support.
-
-  If your buffer fills up with nulls (^@) at some point, it could well
-  be that problem.  That problem does not happen when people use GCC
-  to compile Emacs.  On the other hand, the HP compiler version 9.34
-  was reported to work for the 19.26 pretest.  9.65 was also reported to work.

-  If you turn on the DSUSP character (delayed suspend),
-  Emacs 19.26 does not know how to turn it off on HPUX.
-  You need to turn it off manually.

   If you are running HP/UX release 8.0 or later, you need the optional
   "C/ANSI C" software in order to build Emacs (older releases of HP/UX
   do not require any special software).  If the file "/etc/filesets/C"
   exists on your machine, you have this software, otherwise you do not.

-  In this context, GSV4 and GSV4i are alternate names for X11R4.
