All this have been discussed some time or another in this list. Basically the 
matlink/sf binaries are for people who do not have (or do not know how to 
install) a cygwin tree. Things of course change with time and I agree with you 
that cygwin is now much easier to install. There are cygwin binaries lying 
around that can be installed into an existing cygwin tree.

This page

has a lot of relevant information.
