Hi Nick,
So maybe I'm misunderstanding something, but the issue seems to be that
unsigned char is promoted to 'unsigned char *' by Clang and probably
unsigned int or int by gcc.
No. This is extremely well defined behavior in C. In C, integral
types are NEVER promoted to pointer to integer types, only to larger
integral types through rules more complicated than the correct flags
to pass to `tar`.

Ah right. Thanks for the correction. So looks like bool won't work for
the same reasons. But unsigned int should work right? But then again
this is a boolean value and if we want to be paranoid we can simply
tweak the 'c = h3' assignment to be something like:
c = !!h3;
So in the end, I'm happy with int or unsigned int.
