[boost] Extra file in boost serialization for 1.82.0

Hi, I noticed that under boost/serialization, there is a file "collection_size_type copy.hpp" (notice the space in the file name.) Comparing it with the contents of collection_size_type.hpp, it looks like "collection_size_type copy.hpp" is newer. Can someone verify which one is the correct collection_size_type header file? Thanks, Bryan
