In fact, I am sure lots of people (a vast majority) are running Cygwin (or Mingw - a clone of Cygwin) apps on their Windows boxes without even realising this. Cygwin works quietly behind the scenes here.
Using Cygwin as an environment is a completely different thing, and it could be less popular than virtualisation such as Virtualbox or VMWare - but that's irrelevant, as it is not needed to run an Cygwin-based application. > > > > > Also, note that many parts of Sage are not developed by Sage > > developers, e.g. Maxima, GAP.

You will have to convince GAP team to make and maintain such a port... [...] Cheers, Dmitrii
