Cygwin is ALWAYS well behind. But I have had no problem building gcc 4.2.x using cygwin (I used gcc 3.4 to build gcc 4.2.1, and 4.2.1 to build 4.2.2). If you need 4.2.x to do your cross build, you can build it native first, and then do your cross build (unless your cross compiler needs something not in cygwin - I wouldn't know since I don't attempt building a cross compiler). If you want, I can post the configure parameters I used.
