Have you ever considered or will you consider deprecating char, int, long, (s)size_t, float, double and etc in favour of specific length types?
Will you ever add / have you considered adding [su]\d+ and f\d+ as synonyms for those mentioned stdint.h?
Since char is signed on most platforms, arm eabi being an exception and even there it's really just a matter of compile time flags, will you ever just drop char from being able to be either and just say it's signed, as int is also signed?
Will you ever define / have you considered defining signed overflow behaviour?
