Ah, I see. Sorry, I have an own process of building which goes back to 3.4, which uses these old makefiles. Didn't mention that they are outdated. Removing them would help bringing attention to the fact that something changed. Thanks for the clarification.
I'm running Windows 11 Pro 22H2. But I'm builded it for myself with the Visual Studio 2015 builder. No idea why it did not load with ;2, only wanted to let you know.
windows makefile for 64bit build needs an additional PLATFORM line to work
Windows makefile seems to have a typo in mt.exe line to add manifest to dll
