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.
