Is the inttypes.h header builtin or it's in libc? How about

yep, checked and wrong from my part: The definitions in <stdint.h> put requirements on the types it names, so int16_t must have a width of exactly 16, and INT16_MAX must be 32767. Butthere are no equivalent requirements on types such as int24_t or int128_t. So it is possible for int24_t to be a 16 bit type, or int_least128_t to be a 64 bit type. This is not in the interests of either the implementer or the user of an implementation. https://www.open-std.org/jtc1/sc22/wg14/www/docs/n851.htm

Explain this platform dependency. What exactly do you mean by that? Is it related to OS? ARCH? 32bit or 64bit? What are those platforms that make exceptions?

Byte didn't always mean 8bits, so some platforms used different widths when referring to bytes, but nowadays it is more or less normalized that byte means 8bits

But stdint types are not. uint8_t is literally 8 ...

One more detail - these are minimally guaranteed sizes of each datatype. The maximum is another thing
