make header src/shread/mo_hash.hpp guarded

[anonymouspc]

Header src/shared/mo_hash.hpp is unguarded.

Most times it works. But recently I'm trying to compile boost/locale into a C++20 module. I found this file better be guarded in this compiling-case, as C++20 module treats function-declarations in .hpp files as translatable ones (which cannot be multi-defined).

One tiny change: #ifdef xxx #define xxx to make header mo_hash.hpp guarded.

Thank you!
This is an amazing library and I will start it :)

Makes sense, thanks!

If you get the module working please reach out to the Boost mailing list as there have been discussions on how to best approach this
