Peter, this comes up so often, I wonder is it worth while "hiding" that 
optional dependency behind a #define, as in:

#define BOOST_SP_QA <some-header.hpp>

#ifdef BOOST_SP_USE_QUICK_ALLOCATOR
#include BOOST_SP_QA
#endif

Of course I have no data on how often that dependency is actually needed (or 
not).
