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