The compiler is technically right in warning, but the 'solution' proposed by the
OP is not correct.
When passed through ..., unsigned char promotes to 'int', not 'unsigned int'.
Likewise for unsigned short, when int is larger than short. If it were to
matter whether va_arg were handed 'int' vs. 'unsigned int', then PRIu8 and
PRIu16 should technically be "d" rather than "u" to match the type of the
argument promotion being used. But for all practical implementations, 'int' and
'unsigned int' are the same width (or put another way, calling printf("%u",int)
works just fine on the platforms that glibc target).
In short, I agree with Ulrich's decision to not change the current code base.

There is nothing wrong with the current definitions. If your compiler issues
warnings this is your problem.
