Strangely, I've found that this fix makes the X server unstable on my 
system.  The server just crashes after some time (ranging from 3 minutes 
to 30 minutes), and it writes nothing to the log file when it does this. 
  The X icon disappears from the task bar and all X windows close. 
Occasionally the XWin.exe process continues running and I have to kill 
it from the Windows task manager.

This was already the case with X11R7.4.  But a difference with R7.5 is 
that the checkX command doesn't even serve its intended purpose, i.e., 
xterm never starts.  I tried adding --debug to the checkX command, but I 
don't see any indication of a problem there.  Here's the output:

checkX.exe DEBUG: displayname : '127.0.0.1:0.0'

Simply commenting out the line involving checkX in startxwin.bat solves 
the problem.  I'm satisfied with this workaround for my own purposes, 
but I'm also happy to do whatever I can to help debug this if it turns 
out that other people have the same problem.  I'm attaching the log file 
and cygcheck output.
