Without the change, I can see the following error report:

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.0/../../../../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o): in function `main':

As far as I understand it, the problem is that MinGW expects main()/WinMain() without -municode, but the code uses wmain()/wWinMain().
