Problems with building GHC 7.8.3 on Windows

[Marek Wawrzos]

I have finally builded GHC 7.8.3 on Windows. The wiki page with MSYS2 that
you linked to proved to be useful reference. Indeed using the latest 64 bit
MSYS2 as building environment solved my problems. However there are some
issues with the instructions presented:
-- the MSYS2 package that is linked to in the page fails to initial update.
Using the latest official MSYS2 package does solve that (
https://sourceforge.net/projects/msys2/files/Base/x86_64 );
-- initial update has to be done along the instructions from
http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/ ;
There are some error outputs during initial update but they do not seem to
cause any harm
I thing it might be a good idea to give stronger encouragement to use MSYS2
on the page with Windows-specific instructions. It suggests that old MSYS
can be used successfully while it apparently fails and is not supported.
