rebase -OT file - contains list of paths to all built DLLs - uses the 
existing database to relocate your DLLs above existing Cygwin uses.

You may not be installing much with Windows Setup but may want to ensure 
you uninstall any stuff like Adobe Flash, Adobe Reader, Oracle Java, 
MS Silverlight, games, other "conveniences", "freebies", utilities, etc. 
pushed on you. You may be able to uninstall MS SQL Server, its CLR, SSDT
but don't know impact. You have to keep MS.NET, PowerShell if installed 
as they may be used by MS processes.

and linked github forks I found informative and useful - key to customize 
as YMMV.

You can download Cygwin snapshots: dll only, dbg, pkg, src, directly from 
https://cygwin.com/snapshots for x86{_64,} - instructions given on page.
