Mingw-w64

Mingw-w64 is an advancement of the original mingw.org project, created to support the GCC compiler on Windows systems. It has forked it in 2007 in order to provide support for 64 bits and new APIs. It has since then gained widespread use and distribution.

The development and community are very active and welcoming with new contributors every month and simple installers.

Version 8 has been released

v8.0.0: 2020-09-18

Notable changes:

New Hyper-V headers and libraries by Biswapriyo Nath
Many headers updated from Wine by Jacek Caban.
ARM math improvements by Martin Storsjö
floating point fixes by Liu Hao
many *printf compatibility fixes by Liu Hao and Martin Storsjö
massive Windows App Store API updates by Steve Lhomme

Edit: I figured it out. The problem was with my make.exe hack. I changed the reference in my build system to call mingw32-make.exe directly rather than forwarding arguments from a fake make.exe and it works now. I had gotten that advice about forwarding off the internet somewhere, but it's not a good solution for my case. I'm not clear on the Wiki2 advice for using make: https://sourceforge.net/p/mingw-w64/wiki2/Make/ Just copy any of the *make.exe files to <mingw64>\bin and you're good to go.</mingw64>...

Do I download or build them? If I need to build them, could anyone kindly link instructions that will work for 64-bit Windows?

https://github.com/Microsoft/DirectXTK/wiki/ComPtr#constructing-assigning-and-copying-comptr also makes this explicit. It says: If you want to give a raw pointer to a ComPtr without changing the reference count, you need to use Attach.
