 77/* Historically, the keys in _PATH_MP_DB/_PATH_SMP_DB had the format
 78 * `1 octet tag | key', where the tag is one of the _PW_KEY* values
 79 * listed below.  These values happen to be ASCII digits.  Starting
 80 * with FreeBSD 5.1, the tag is now still a single octet, but the
 81 * upper 4 bits are interpreted as a version.  Pre-FreeBSD 5.1 format
 82 * entries are version `3' -- this conveniently results in the same
 83 * key values as before.  The new, architecture-independent entries
 84 * are version `4'.
 85 * As it happens, some applications read the database directly.
 86 * (Bad app, no cookie!)  Thus, we leave the _PW_KEY* symbols at their
 87 * old pre-FreeBSD 5.1 values so these apps still work.  Consequently
 88 * we have to muck around a bit more to get the correct, versioned
 89 * tag, and that is what the _PW_VERSIONED macro is about.
