Sorry Leonid Vladimirovic if that affected your installation or work.

But I didn't believe Cygwin Setup would replace packages that are still 
dependencies of installed packages, unless you explicitly ask it to 
remove obsolete packages, rather than unneeded dependencies.

Unless it was due to my marking libidn12 as obsoleting libidn11?
Maintainers: is that something that we should not do on a package ABI 
break?
How should maintainers handle such situations in cygport?

I would like to know the correct approach to take to mitigate this and 
future such situations before I create a curl -2 package release.

Packages impacted would include:
