Thank you for that on-topic suggestion of Imagemagick's "transform"
command, even as I think the helpful suggestion from the alt.comp.freeware
poster of how to force the aspect ratio in an Irfanview crop is likely to
be the easiest we'll find for Windows aspect-ratio cropping.

I think of Imagemagick as a command-line tool, but your suggestion deserves
adequate exploration, where the command of choice seems to be the 'crop'.

Here is an example from that Imagemagick manpage:
  convert rose: -crop 40x30+90+60  crop_miss.gif

This seems useful particularly as a batch command, when you know the
position of the crop you wish to make on a bunch of files (which isn't the
case in my original question). 

However, it's a useful alternative that should be noted, as ImageMagick is
known to be powerful and fast freeware.
