A bit of a stab in the dark, perhaps change the region around  
timer.cpp(109) to

     chrono_start = chrono();
     while ( double( chrono_wall() - chrono_wall_start ) <  
chrono_wall_scale*4.0);
     chrono_end = chrono();

I'm now doubly confused as it appears to be complaining about the  
return type of std::clock, (the default wall-clock timer).  Maybe I  
can get my hands on a windows machine and compiler tomorrow....
