Yes, let's take this to Ruby-Talk so we can all participate. Most of the 
open source projects I deal with on Windows have gone to || stayed with 
MinGW/MSYS and its friends. Ruby seems to be the exception. I remember 
the past discussions and my own point of view was that it didn't really 
matter to me as long as the gems && other C/C++ libraries were available 
in binary form and in source form if their licenses required it. I don't 
*need* to build from source on Windows, although I wouldn't refuse the 
opportunity to do so.

I am in the process of phasing out Cygwin usage at my day job. I brought 
it in as a crutch and it has become a maintenance nightmare. The worst 
part of it is that it hoses up file and directory permissions at the NT 
level if you aren't careful (and I haven't been). :)

So while I know that VC8 is a "better" compiler than MinGW/MSYS, what 
other open source projects, if any, use VC8? How many others use VC6? 
What are the licensing gotchas on the Intel compiler? In general, are 
open source projects on Windows doomed to be second-class citizens? :(
