Thanks for your info on the installed.db.

As I replied to another mailing list member, I recognize the problems of 
editing files under the package manager's control. If installing from 
source weren't buggy (that I *should* report upstream) I would do that 
rather than edit the files installed by cygwin.

The bug is fixed upstream, but only in a release candidate. It would be 
nice if cygwin had a real way to freeze a package. For example, when you 
freeze a package in Arch Linux, everytime you update your packages it 
prints a warning listing packages you have frozen. This way, each time 
you run an update you see the warning and can consider again if you need 
to have the packages frozen, or if something starts acting funny you can 
ask yourself, "I wonder if the problem is caused by these packages I 
have frozen".
