a self-contained Sage package for Windows/Cygwin would anyway include much more stuff than such a package for Unix...
If on the other hand one goes for having Sage installed on a working installation of Cygwin (which is much more realistic option), I see no harm in requiring system-supplied libiconv. The "default" installation of Cygwin is very easily modifiable, and not very well-defined anyway. I am sure it is easy to supply a configuration for the Cygwin package manager to tell it to download what is needed.
