There are 5,786 packages in Cygwin, and the pre-test state was closer to 
1,000.  Making several thousand "Uninstall" selections isn't much of a 
solution.

I ended up doing the reinstall-and-merge.

I told myself that it was about time I got my Cygwin 32 directory named 
c:\cygwin32 instead of c:\cygwin, since I've also got Cygwin 64 installed.

Plus, there was an awful lot of cruft in that old tree.  Part of the 
problem was obsolete empty packages like g++-4, which setup.exe was told 
were part of my dependency set, but which it couldn't remove.  Once I 
started hacking on installed.db, I knew it was time to nuke and pave.
