Since this variable is not gets redefined very often in the user projects, may be it is possible to introduce include guard that depends on this variable as well? #ifdef BOOST_FUNCTION_HPP_##BOOST_FUNCTION_MAX_ARGS #define BOOST_FUNCTION_HPP_##BOOST_FUNCTION_MAX_ARGS ... #endif I remember I got quite a speedup on windows compilation when I put "simple" #ifdef BOOST_FUNCTION_HPP guard into the file.

I haven't tested it, but looking at the code I think you can include boost/function.hpp multiple times and if BOOST_FUNCTION_MAX_ARGS is (re-)defined between any of those inclusions then everything still works as you'd hope.
Yep, that's why it doesn't have include guards.
