There are no duplicate *.exe commands.  All Cygwin executables contain the
exe extension as Windows prefers.  Cygwin tries to make things easier by
mapping "cat" to "cat.exe", for example, which is why it may look to you
like there are both in the Cygwin environment.  But look at 'c:\cygwin\bin'
in the Explorer and you'll see all the commands have the .exe extension.
If you get rid of one, you get rid of the other since they are the same.
Now, to anticipate your next question, '/usr/bin/cat.exe' and '/bin/cat.exe'
are not duplicates either.  See the results of typing 'mount'.
