if the configure/makefile stuff is cleaned up so everything works then
IMHO this should be applied
it would also be interresting to benchmark the individual functions with
START/STOP_TIMER to see which are faster, furthermore we support many IDCTs, 
so if you benchmark them dont just benchmark the default one and IPP but all
another interresting thing would be to add IPP suport to dct-test.c so we
could see how accurate it is
