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.
