Run rebase-trigger full then shut down *ALL* Cygwin processes: check Task
Manager Details tab Image path name column for process paths under Cygwin root
and kill.
If rebase-trigger full fails, create /var/cache/rebase/fullrebase.
Then download and run Cygwin setup and let all the postinstall scripts complete.
