FWIW, the fact that cygwin's setup has problems working doesn't not stop you from *trying* cygwin - it doesn't do very much more than just unpacking tar.tgz files, which you can do manually. And for many command-line utilities, just have the exe and the dll around is enough.

However, I found that cygwin version of a few utlities does not work correctly uner wine (it obvious does for some under genuine windows). While the mingw/gnuwin32 equivalent, do. echo and cat were two I had problems with, when I accidentally let some 3rd party's installer put cygwin's cat/echo in front of gnuwin32's cat/echo in my $PATH under cmd.

Also, I believe MSYS and Mingw do not depends on cygwin. cygwin and msys/mingw are rather different. For building windows applications, you really want to stick with mingw if you can.

And, I found cross-compiling works well enough that I don't bother with having a mingw-based dev system under wine. And if I need MS VC specifically, that works well under wine so; so there has not been any need for running mingw or cgywin under wine for a while. I can tell you from first hand experience that mingw gcc/g++ works well under wine, but many times slower compared to cross-compiling. I think the speed problem comes from fork/exec being slow in wine.
