What is the proper type to use in an Ada binding
for a C method that returns a C99 bool?
Whatever the answer is, it should be used to define Interfaces.C.Bool.
(I don't know what GCC's options for representing _Bool are, sorry.)
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. :)
