FYI, bash (which is what I assume is invoked by cygwin.bat) doesn't honor
PATHEXT.  Cygwin has a special feature that looks for a .exe (and only
.exe, .bat won't be found either) if the file with null extension does not
exist.

I'm not sure about cmd.exe, probably depends on your version of the OS (or
maybe MS deprecated it altogether).
