Yes.

It's "mingw.org" and "mingw-w64", not "mingw32" and "mingw64".
You can google for "mingw-w64 vs mingw.org", that should explain the situation.

CPython is the Python implementation from python.org

W32-CPython is CPython built with MSVC and distributed by python.org
MinGW-CPython is CPython built with MinGW (or MinGW-w64) (which requires a
number of patches at the moment, there are issues open on Python bugtracker
for this).

Probably not (i've poked mingw-get a bit once, then just gave up).

I don't know what the devs think.

Cygwin is a good method. MSYS2 is even better, IMO. MSYS - not so much.

And on top of that you need, orthogonally, a toolchain, which could be
MinGW.org or MinGW-w64. As you've experienced, MinGW.org at the moment is not
very well-supported, unlike MinGW-w64.
