Pierre,

First off, there is a patch (in?) that allows sparse files on NT+, so it
may not be that much of a deal on those systems (unless the indices are
dense enough, which is not going to happen).  Is the above likely to be a
problem on Win9x?

Secondly, is lastlog accessed through a uniform interface (library), or
does every application implement its own?
