PATCH: zsh-3.1.5-pws-9: Cygwin, hash foo.exe as foo

["Matt Armstrong" <mattarmst@xxxxxxxxxxx>]

Under DOS/Win32 most executables have a .exe extension.  When running 
under Cygwin, the command hash gets filled with all the .exe versions of 
the names.  This works fine, except when CORRECT or CORRECT_ALL are set 
-- zsh tries to spell correct when you don't type the trailing .exe.  
This is inconvenient.

This patch introduces a _WIN32 specific change.  If a file foo.exe is in 
the path, the patch causes both foo and foo.exe to be added to the 
command hash.

I didn't use __CYGWIN__ because I think this is useful for both UWIN 
(which may define _WIN32) and a native port (which does define _WIN32).
