Right, there's a big mea culpa on my part here - Uwe managed to wake me up 
to my own idiocy.  Obviously I had a case where PkgA Suggests PkgB and 
PkgB didn't exist for Windows.  When I saw that PkgA failed to install on 
Windows, I always quickly assumed that was the case, but there was another 
goofy linkage between the two packages that I didn't intend to be there. 
PkgA fails to install in the absense of PkgB no matter what the platform.

Considering that my use case for this has been debunked and it's the only 
valid one I can think of, I'll shut up now :)
