commit 77ddbf45b5c16faeb0c7247ded8c7a5f6fb59b19
Author: Jon Turney <jon.turney@dronecode.org.uk>
Date:   Tue Nov 22 16:05:58 2016 +0000

    Strip symbols to setup.dbg
    
    As noted in https://cygwin.com/ml/cygwin/2016-11/msg00254.html debugging the
    distributed setup executable is a lost cause at the moment.  Preserve
    symbols so it's not quite as hopeless.
    
    Note: to debug the distributed setup executable with gdb, it will be
    necessary to decompress the setup executable with 'upx -d', and, if the .dbg
    file has been renamed to match the renamed setup executable, explicitly load
    it into gdb with the 'symbol-file' command.
