Probably the record that some /usr/lib/sasl2 stuff got installed was lost
somehow.  A couple of days ago, I found my computer with an inconsistent setup
database (which showed a lot fewer files/packages than were actually installed),
so I got very few of the offered package updates displayed.  I investigated and
came up with a script to fix this (consider this version 0.0.1 and under GNU GPL
v3) state (see below).

I'd also appreciate if setup.exe recorded file hashes so I can see which files
have been altered since initial installation with a (to be written) cygcheck. I
know, volunteer efforts and spare time, but I'd still mention it.

Here's the script.  Crude, works for me in a particular situation, so no
warranties whatsoever (you're free not to use it):
