32bit support?

[RazielXYZ]

Would there be any interest in 32bit support for the library? I am aware that some features (primarily anything relying on marked_ptr) cannot compile/run on 32bit, but as far as I can tell many things would be able to, with a few additions and modifications to ifdefs, both to allow building on 32bit and to exclude the parts that would not work. I would be willing to look into this further and test.

Edit: Actually, it seems all reclamation schemes seem to depend on concurrent_ptr which in turn depends on marked_ptr, so this would be quite a bit of an issue.
