BSD 4.3tahoe

The X11R2 distribution wasn't included with 4.3BSD-tahoe due to
space considerations.  It is available from MIT by anonymous ftp
from expo.lcs.mit.edu or on tape distribution.  Minimal changes are
required to compile it under this release.

The X11R2 code was compiled on a VAX, and servers for Digital
Equipment Corp. display hardware QDSS and QVSS were built (see
QDSS.README for details).  The following is a list of changes that
are necessary to compile X11R2 servers for QDSS and QVSS.

1)	Apply patches 1 through 33 to the stock MIT X11R2 distribution.
	(patches available from expo.lcs.mit.edu via anonymous FTP)

2)	In X11R2/server/ddx/dec/qdss/Ultrix2.0inc.h, comment out the
	reference to "<sys/devio.h>".

3)	Due to changes in preparation for ANSI C, the ioctl macros 
	have changed.  In X11R2/server/ddx/dec/qdss/libtl/tl.h add
	single quotes around the letters in the ioctl declarations.

4)      In X11R2/server/ddx/dec/qdss/qdpushpxl.c there is a null
	storage declaration which the Ultrix compiler doesn't mind,
	but the 4.3BSD-tahoe compiler does.  Move the null storage
	declaration inside the "#ifdef notdef" section of code.

---------------------------------

5)	X11R2/server/os/4.2bsd/connection.c has a bug which causes
	the unix domain socket to have the wrong permission, and clients
	can't connect to it.  Add a umask(0) before the bind().
