This is a known limitation of setup*.exe. Its dependency checking is
focused on installing, not uninstalling. As a result, you can sometimes
get into a dependency loop like this when you're trying to uninstall.
For now, there is no solution using setup*.exe. You can, however, remove
the files from the packages you don't want by hand by using the list of
files it installed as returned by *cygcheck -l <package name>*. That
should take care of the majority of what was done in the installation,
if not all of it.
