Thanks for the suggestion.  This is indeed a build glitch, but I don't 
understand what's happening yet.  If I unpack the emacs-23.2 source and 
just build it (./configure && make) the bug is gone.  But normally I 
build emacs for Cygwin by using a packaging tool called cygport, which 
(among other things) does an out-of-tree build.  I don't know if this is 
causing the problem.  My build of emacs-23.1 also used cygport and 
didn't exhibit the bug.  So I have to keep investigating.
