The code that has bool or _Bool being 1 byte is wrong, it is 4 bytes. The host
compilers have always done this, as should all the FSF compilers. Do you see
another other than this:
$ cat t.c
int sz = sizeof(_Bool);
$ gcc -arch ppc t.c -S -o -
.machine ppc7400
_sz:
.long 4
with either the host compilers or gcc? I'd expect that there is code that uses
char or unsigned char and expects that to be abi compatible with bool. It
isn't. _Bool would be however. In sizeof expressions, one should use
sizeof(bool) instead of an explicit or implicit 1.
