I don't have access to this particular environment, though I do
use NetBSD/macppc.

You might search a bit for clues with

gcc -E -dD - </dev/null | sort | less

and

gcc -E -dD <<EOF | sort | less
#include <sys/types.h>
EOF

On NetBSD/macppc the latter includes

typedef long long int __int64_t;

and

typedef __int64_t int64_t;

among others using the __int64_t typedef.

If I've understood correctly, the names prefixed with two
underscores are supposed to come "from the implementation", be
that either from the compiler itself or the "system headers" (I'm
a little vague on the exact defintion).
