better test case
Thou shalt use IMPLICIT none, especially if you think you don't need it...
Here's a better test case, which actually tests the right thing.
Timings with 4.4 on i686-pc-linux-gnu:
matmul = 15.596974 s
subroutine with explicit interface: 3.6842318 s
unrolled subroutine with explicit interface: 3.3522091 s
inline with sum 3.3602085 s
