apt-cyg install bc

Answer 2

You should be able to use setup.exe w/o the GUI:

setup.exe -q -n -N -d -R c:\cygwin -s http://yourFavoriteMirror \ 
-l c:\localPackageDir -P  <comma-separated list of packages to install>

This is from cygwin mailing list (and follow up post)

Answer 3

You can run setup.exe again and add/remove package, as well as the first time ;)
