    The dumb Visual C++ sizeof(int)<sizeof(void*) decision means some arrays can't safely be indexed by int.

        GCC and Visual C++ 64-bit decisions were aberrations that broke good code. sizeof(int)==sizeof(void*) in the 16&32 bit eras.

        int and pointers should always be safe by default, while low level optimization can be accomplished with explicit int8/16/32/64.

        Dozens of built-in integer types; the obvious one can't index arrays safely, and none are the actual integers!

        Also, I don't know of *any* current 64 bit ABI where sizeof(int) >= sizeof(void *). MSVC++ is hardly alone here.https://wandbox.org/permlink/0es1WRuN8MTlZiuB …

        In both the ILP64 and SILP64 datamodels sizeof(int) == sizeof(void*), but you won't find that on any desktop.

        In my mind "short", "int" and "long" are deprecated. I only use integer types ending in _t if possible.

        And that isn't about performance, it's about well defined semantics allowing me to reason about bugs in code.

        Is there any general purpose 64 bit platform where int is a 64 bit integer type?
