Dos Windows on 386i with X11R3

[arran!rwu at rutgers.edu]

I apologize for omitting some important details on how to make running X11
under overview work correctly. Hopefully, the following will provide the
necessary information. If not, please let me know. By the way, for the
386i, the Meta key mentioned below is really the left-diamond key (next to
the spacebar).

The following information is from Dana Chee (dana at bellcore.com):

Ron,
	You have to define SUN_WINDOWS
before compiling to get an Xsun which will run under overview.  The
Meta-L2 option to stop it is a patch I provided for Jim (and anyone
else who wanted it).  You can get it by looking in
/fs/X11/export/X11_R3_Src/updates/metakey.suntools.

[ I have appended the above mentioned file to this letter. Ron ]

Jim had two directories that used a different Imakefile.  in
.../ddx/sun, the Imakefile used SERVER_DEFINES (no SUN_WINDOWS), and
in .../ddx/sun_windows, the Imakefile used NEW_SERVER_DEFINES (has
SUN_WINDOWS).  I really don't think we need to make both, since having
it have the sun stuff compiled in isn't a problem.

------------  report.metakey ----------------
VERSION:
	X11 release 2

CLIENT MACHINE:
	Sun 3/75

CLIENT OPERATING SYSTEM:
	SunOS 3.2

DISPLAY:
	Sun

SYNOPSIS:
	Add Meta-L2 support for running X under Sunview.

DESCRIPTION:
	These diff add the Meta-L2 support present in X10R4 which
        allowed an X server running under Sunview to return to
	Sunview by typing Meta-L2.  When the overview icon was
	clicked, the X server was restarted.

	Affected files:
		clients/xinit/xinit.c
		server/ddx/sun/sunInit.c
		server/ddx/sun/sunKbd.c
