I can't reproduce this.  I tested both emacs-X11 and emacs-w32, on both 
32-bit Cygwin and 64-bit Cygwin.  Can you think of anything on your 
system that has changed in the last few days?  And have you tried 
starting emacs with the '-Q' option to rule out a problem in your 
initialization files?

You should also attach cygcheck output, as suggested at 
http://cygwin.com/problems.html.
