Dave's running this command on a self-compiled version of setup. The
setup on the Cygwin site is compressed with upx, which mangles all strings
(except the PE header). So, one way to get version information into setup
is to use the "Version:" tag in the PE header (or whatever it's called),
but that will only work for the newest setup versions -- the older ones
will have the "unextractable version" problem.
