I was asking about "MSYS2/MinGW-w64".

You seem to be confusing mingw.org (http://www.mingw.org/wiki/getting_started) and MinGW-w64 (http://mingw-w64.sourceforge.net) and your rant seems entirely directed at mingw.org.

The software distribution I was asking the parent poster about is MSYS2 (http://msys2.github.io/ and http://sourceforge.net/projects/msys2/), do please come back with constructive criticism on that project if you are interested enough to investigate further.
