What I have done is built a version of flex 2.5.35 with Cygwin, and
bundled the .exe with the Cygwin DLL (the only other thing it should
need, for our purposes) in a zip file. It can currently be fetched from
<http://developer.postgresql.org/~adunstan/windows-flex-2.5.35.zip>.
That way people won't have to do a full Cygwin or MSys install to use it.
