Yep, and still is, as I said. We don't use any MinGW functions at
all, so nothing changes in this regard, no need to worry about
MinGW's 80-bit `long double`, their different C++ mangling, their
.a static library format or their DWARF debug info. You're still
targeting windows-msvc. We only need the MinGW .def files because
Microsoft shamefully doesn't allow distribution of their static &
import libs.
As stated in the readme, using the MS toolchain is obviously
still supported.
