The while statement?

     chrono_start = chrono();
     while (chrono_wall()-chrono_wall_start < chrono_wall_scale*4);
     chrono_end = chrono();

Hmm.  Depending on what the type of 'ticks' from cycle.h is (that's  
what you're using right) that should just be a large integer type.   
Perhaps try with the util::high_resolution_timer, which is of type  
double().

Otherwise do you think the compiler is getting confused between the  
name of the template parameter 'ticks' and the type 'ticks'?
