Cygwin, for better or worse, is a rolling distribution. If that doesn't
suit your needs, you'll have to come up with your own mechanism to lock
things the way you want it to.
In this particular case, Cygwin 3.0 does add new API and if any new
package uses it, then it will become incompatible with the older Cygwin.
While I can't speak for other package maintainers, I usually fully
update Cygwin before building new packages.

…which was built long before the API change in question.

No. You need to keep the dependency chain ordered so that all
dependencies of the package to be installed are older than the package
itself. While setup now supports versioned dependencies in principle,
this is not currently used, so you'll have to do this via other means.
