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?

This is https://github.com/boostorg/serialization/issues/237 https://github.com/boostorg/serialization/issues/237 And https://github.com/boostorg/serialization/issues/221 https://github.com/boostorg/serialization/issues/221 Sadly, this has been a problem for several releases. — Marshall
