OK - I've looked at this a little bit.

I made adjustments to more easily support all C++ compilers from C++98
to C++14 + and to factor common code from vector, valarray, native
arrays, and who knows what else. One of the things this entailed was to
put the implementation of an "array_wrapper" in a separate file. This
is more general than the concept of an "array". It also includes the
definition of "make_array" which perhaps should be called

So I think the best would be for ublas / storage to replace

#include boost/serialization/array.hpp


#include boost/serialization/array_wrapper.hpp

A word of caution - I'm actually not quite done with this but I don't
think the array_wapper concept/definition will change so I think it is
safe to make this change. Unfortunately, this will mean that
serialization and ublas will have to be merged to the master at the same
time. I realize that this is not ideal - but still ...
