Yes, I've figured it out.
It only happens when "setopt correct" is set, the first instance of a file 
in the PATH has a .exe extension, and the second doesn't.  Here's how to 
reproduce it.

I created an executable /tmp/a/dummy.exe which prints "a", and a script 
"/tmp/b/dummy" which prints "b".

Move all zsh initialisation files (/etc/z* and ~/.z*) away, and open a new 
zsh window.

Now type:
         % PATH=/usr/bin:/tmp/a:/tmp/b
         % dummy
         a

Open a new zsh window, and type:
         % PATH=/usr/bin:/tmp/a:/tmp/b
         % setopt correct
         % dummy
         b

Conclusion: don't use "setopt correct" under Cygwin. :-(
