 *
 * NOTE: This needs to be in a public header so that both the library
 * implementation and client applications both agree on the same types.
 * Otherwise we get undefined behavior.
 *
 * Use the "best" types that each platform provides. Currently we truncate
 * these intermediate representations for compatibility with the git ABI, but
 * if and when it changes to support 64 bit types, our code will naturally
 * adapt.
 * NOTE: These types should match those that are returned by our internal
 * stat() functions, for all platforms.
