Yup, it is dangerous -- Cygnus has run into problems with this kind of
stuff before.

However, we do need to find some way to address the problem of stale
files in the include installation directory.  Until we do I highly
recommend folks wipe it out before doing an install.

Well, another approach would be to issue a warning and demand user
intervention if files are found in the dir which aren't part of
the current distrubtion.  I don't know how feasible this is.
