Running cygcheck with appropriate options just points out the problems, that you
can then fix by doing reinstalls or upgrades with setup.
If anything appears to go wrong during setup, just be patient and let it finish.
If anything seems wrong while testing, just exit all Cygwin processes, and rerun
setup again.
On my last setup run to upgrade packages, I forgot I had a Windows task
scheduled, which runs a Cygwin script, that creates dozens of background Cygwin
processes, each of which runs dozens of Cygwin commands and other scripts. I
just let all processes in that task, and setup, finish; then immediately reran
setup, accepting all the defaults, and allowed that to complete, after which
Cygwin/X with a mintty terminal started normally.
