In theory that should be solved by the dependency to cygwin. Cygwin
depends on base-cygwin, all other packages depend on cygwin. The
problem is just that dependency loops can break that.

Per its setup.hint file it depends on nothing, just like base-cygwin,
and both packages request that they don't get an automatic dependency
to cygwin added.

Achim, can you give a management summary how your proposal works?
