What do you mean ?  There are ABIs, and we expect all used compilers to
follow common arch ABI.  Old psABIs date back to time where _Bool
did not existed yet, but now it is ubiquitious.  E.g. both i386 and
amd64 require _Bool have a representation by single byte, with the
byte alignment.

Can you give exact examples of the inconsistencies, on any platform,
regardless of our tier ?
