I've never found them awkward to work with and every *nix I've ever developed
on had stdint.h. If Windows doesn't thats Window's problem.

This is why it popular to just do:

Popular maybe in WindowsWorld. Why as a unix dev would I do that when
standard typedefs already exist for this exact purpose?

stdint.h et al are just ungainly bolt-ons, not fully supported by the
language.

Whats that supposed to mean? The core language itself supports very little.
Do you not use libraries at all?

So somebody eschewing those ugly macros and using "%ld" to print an

What makes you think they're macros?

MacOS:
stdint.h
_types/_uint64_t.h
typedef unsigned long long uint64_t;
Linux:
stdint.h
#if __WORDSIZE == 64
typedef unsigned long int       uint64_t;
#else
__extension__
typedef unsigned long long int  uint64_t;
#endif
