I do not think this is really worth it.

    printf("%s%06o %s %d\t", tag, (unsigned) ntohl(ce->ce_mode), ...

is perfectly readable for even old timers about git, as long as
they know traditional C and what ntohl() is.  And ce->ce_mode
even fits in 16-bit, so while we are _not_ supporting platforms
whose unsigned int is 16-bit, the above cast is not losing any
useful precision either.

I think we would want these exact-sized integer types, so if
they are missing the platform ports may want to supply their own
substitute.
