I wonder if this is worth the trouble.  Right now we have a problem in which 
data written to /dev/clipboard in one arch can't be read in the other arch.  The 
fix will appear in Cygwin 3.3.0.  Do we really have to try to make the fix apply 
retroactively in case the user updates one arch but not the other?
