--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
char having the same set of values as signed char is valid.

char is not however a "signed integer type" within the meaning of the 
standard, and so is never a valid definition of int8_t, despite Solaris 
using that definition.
