To the best of my knowledge: * `_WIN32` and `_WIN64` are defined by the compiler, * `WIN32` and `WIN64` are defined by the user, to indicate whatever the user chooses them to indicate. They mean 32-bit and 64-bit Windows compilation by convention only. See: https://accu.org/journals/overload/24/132/wilson_2223/ Windows compilers in general, and MSVC in particular, have been defining `_WIN32` and `_WIN64` for a long time, provably at least since Visual Studio 2015, and in practice as early as in the days of 16-bit Windows. See: https://learn.microsoft.com/en-us/cpp/preprocessor/predefined-macros?view=msvc-140 https://learn.microsoft.com/en-us/windows/win32/winprog64/the-tools Tests used to be inconsistent, usually testing `_WIN32` and here testing `WIN32`. This brings consistency to Windows detection.
