It appears to be unsigned char or at least sizeof(bool)=1
on the architectures I tried this test program on.
#include <stdbool.h>
bool x;
int s = sizeof(bool);
Unfortunately bool is defined to _Bool and that must be
something gcc recognizes. I don't see it in .h files.
So I am only slightly more sure of it than you are. :)
