Re: Building ghc on Windows with msys2

I've updated the configure script to download the mingw distribution on the fly (D339 , #9218 ). I could use some help with a few things: 1. Validating the update to gcc 4.8.3. I tried to run the tests and got some

I'm sure we could make git handle the tarballs, but it just seems like the wrong tool for the job. We'd have to use multiple advanced features of git where a simple wget/curl would do.
