Thanks for the clarification. Okay. Once I've written some code to
unpick which packages are erroneously creating the loops I'll report back.

Next question - :-) - should I report here or in cygwin-apps?

At the risk of getting a SHTDI response, perhaps part of the release
process for setup.ini should include a topological sort on '@
package'/'requires: package ...' pairs to flag up such issues? :-D
