Are you calculating the setup.exe size delta after upx, or are you 
looking at the .ico file?  upx should provide similar benefit as Vista 
PNG icons, as compared to standard BMP style icons.

My reason for asking if we can skip the other sizes was more a matter of 
removing unnecessary work than saving single-digit KB in the binary.

(I tried upx on cygicons-0.dll, by the way, but it apparently broke 
something.  On trying to use my compressed version to supply an icon for 
a shortcut, Windows complains it doesn't contain any icons.  *shrug*)
