Cygwin 3.1.X causes fatal errors

["Ken Turner" <kjt at cs dot stir dot ac dot uk>]

I have Windows 10 64-bit, but am using the 32-bit version of Cygwin for
historical reasons. I seem to have the same problem noted in
https://www.mail-archive.com/cygwin@cygwin.com/msg162929.html. That is,
installation of Cygwin 3.1.X does not work properly. The setup log shows (in
part):

Following this I can no longer run shells nor do a rebase:

  C:\bin\dash.exe: *** fatal error - add_item ("\??\C:", "/", ...) failed,
errno 22

  C:\bin\rebase.exe: *** fatal error - add_item ("\??\C:", "/", ...) failed,
errno 22

I am therefore forced to go back to Cygwin 3.0.7-1 (which continues to work
OK). Any thoughts?
