      As a Windows C++ dev, I’d love to see a win64 API declared which updates to sizeof(int)=sizeof(void*), unsigned char, utf8 only (using new codepage), straight API declarations in one header per Windows DLL with no macro hackery.

      I think using the C int type isn't best practice these days. Use int32_t, or int64_t, or intptr_t, or an easier-to-type typedef of those. Otherwise 👍

      There is a nice world in which int is sufficient for indexing any array that can exist. This is the only low-level definition of int that makes sense. This size_t garbage litters code with all kinds of shady conversions and other accidents-waiting-to-happen.

      The ship has sailed for C, unfortunately: no matter what MSVC does, you have to assume sizeof(int) might not be the same as sizeof(void*) to be portable.

      And if you use intptr_t/int32_t/int64_t everywhere, then you only need to worry about portability to different pointer sizes, not to arbitrary permutations of sizeof(int) and sizeof(void*). Makes it harder to screw up the conversions.

      We should unsail the ship and realign all platforms with more sensible defaults. If we don’t, C++ is going to eventually be crushed under the weight of messes of these types. intptr_t everywhere is silly and pedantic versus another API break.

          Windows has made 2 API breaks with great success: win32 and x64. And one failure, UWP.

          Win32 and x64 were hardly API breaks. They were entirely new platforms at the time, and MS tried to make existing code as easy to port as possible. They haven't even deprecated Win32.
