I did that originally but when I sent out my first version of patches
for review, other developers asked me to use an unnamed union ---
since otherwise the patch would be much, much larger (lots of changes
would need to be made) and that makes it much harder to merge into
either Andrew's or Linus's tree.

What do other people think?  I can go either way on this one.
