You can see the number of boost preprocessor files failing the include guard optimization when running IncludeGuardian <https://includeguardian.io/> over Boost Graph https://gist.github.com/IncludeGuardian/0837719e0d1162d5b50e4c8fed4d3c0d#file-boost_graph-yaml-L345-L749 An example boost preprocessor header can be found here https://github.com/boostorg/preprocessor/blob/667e87b3392db338a919cbe0213979713aca52e3/include/boost/preprocessor.hpp. Note the consistent use of null directives outside of the guard.
