Welcome to the Rockbox Technical Forums!
I can't speak as to that, but here's a link to the next-to-latest version of the installer (they don't seem to offer it on their site):http://dl.getdropbox.com/u/84704/cygwin-setup-2.573.2.2.exe
We don't know how long old versions of the installer will be available for download
EDIT: Aha, found this:http://www.cygwin.com/ml/cygwin-announce/2008-08/msg00001.html
