It's not as bad as it sounds. I keep *all* my installation files ---
native Windows apps, Java, Cygwin distribution and packages, etc. --- so
I can always re-install something.

Hmmm. Since my preference is to have (effectively)

      PATH=$HOME/bin:/usr/local/bin:/usr/bin

I'll manually create a script which removes the obsoleted files. If it
doesn't hose my system <grin>, I'll post it.
