While building the PDF docs for 1.47 I noticed a bunch of Doxygen warnings about mismatched PP directives in the Boost.Interprocess source - warning messages below - should I/we be concerned, or this just a Doxygenism? Thanks, John. M:/data/boost/branches/release/boost/interprocess/permissions.hpp:55: warning: More #endif's than #if's found.
