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