That's what I was refering to.  That effectively means that it can
only be changed between boost versions - one can't just make
the fix on his particular system.

It's still not clear what this should be changed to - if in fact it should
be changed at all.  std::size_t is a candidate - but I was under the
impression that there might be interest in defining a special type
for this - like collection_size_t or ?
