It does.  Currently R can be built under Cygwin, and how to do so is 
documented in the R-admin manual.  But that was not the case a few 
weeks ago, so you need to look in R-patched/R-devel (and Cygwin might 
change again ...).

It was broken from most of 2011 too, for three separate reasons.

Even when it 'works', it is far slower than the native Windows port 
and it fails 'make check' (not handling CR-delimited files, problems 
with wide-characters as Cygwin does not have proper locales).
