I see no reason against choosing a subdirectory structure in which to place 32 and 64 bit libraries. However, if Program Files is the install location, Windows already distinguishes between them: Program Files and Program Files (x86). IOW, if that's the install location, the subdirectories aren't needed (though one can still be used in each location).

I vote for simple, straightforward names, like 32 and 64, for the subdirectories, BTW.

Having said that much, naming the directories with much of the platform and architecture information, while simplifying the library names, would be nicer IME.
