Making Windows application icons on Mac

[Mike Brown]

I successfully used the BMPtoICO utility and was able to add an icon to a
Windows standalone from my Mac.  Unfortunately only the 16 color format
would work.  I am spoiled by the higher quality look of OS X and Windows XP
icons... Is there any way to add a better icon to a Windows Rev app than a
32 x 32 pixel 16 color version?  Is that standard or an outdated format??
