Stay on the 'Curr' (not 'Exp'), click 'View' until you are on the
Pending page, then cycle on the string next to each gcc package until it
says Keep instead of the downgraded version number.

Yes, it's a known pain that setup.exe tries too hard to downgrade
experimental packages.  I still remember the pain of the couple of years
during cygwin 1.5 days where the only working emacs was marked
experimental, and I had to go through this exercise of manually
requesting that it not be downgraded every time I ran setup.exe for
anything else.  Patches welcome.
