I took another practice run at the x86_64 (aka 64bit) directory and got this:
/sourceware/infra/bin/cygwin/upset: Error. Parsing failed. - duplicate packages "xorg-server-extra" detected - x86_64/release/X.Org/xorg-server/xorg-server-extra vs. x86_64/release/X.Org/xorg-server/xorg-server-dmx/xorg-server-extra
