I think they should be rewritten using explicit integer sizes instead.
The use of pointers is IMHO OK here, but instead of using char *,
rather use uint8_t *, etc.
Theodore has been proposing something similar for the EEPROM functions
recently. He also uses explicit integer sizes.
Of course, <inttypes.h> needs my suggested fix applied first. Any
comments about that one?

Nope, except what i've been mentioning all the time: it needs a
volunteer to do all this. avr-libc simply has never been designed
with the idea of using -mint8 in mind, so if you now find -mint8
flaws, most of them are not there intentionally but rather
accidentally.
Of course, -mint8 will always violate the C standard, but if someone
really cares for all the details of it, avr-libc could be probably
made largely compatible with it (and the parts that are incompatible
simply need to be documented then).
