In my experience, Gord's first statement above *is* true.  Even 
though the current setup has been fixed so this problem does 
not happen with new installations, it does not go back and fix 
the problem for people who used the old setup.  The user must 
manually find the missing DLLs, or use a command like this:

cd / && ls `zcat /etc/setup/*.gz | grep -v etc/postinstall` >/dev/null

Then setup must be forced to reinstall the appropriate packages; 
it does not automatically recognize that they need to be updated.

Incidentally, IMO Gord's solution to completely reinstall Cygwin 
from scratch is overkill.  Finding the missing DLLs and having 
setup reinstall them is much easier and should be just as clean.
