Closing as fixed. Timings for a small test program comparing matrix
multiplication done manually vs. libgfortran for real and complex.
Results without the committed patch (-O3 -funroll-loops, 1.6 GHz Pentium-M):
Manual real: 0.2140
Real matmul: 0.2390
Complex manual: 0.8259
Complex matmul: 3.8654
with the patch:
Manual real: 0.2130
Real matmul: 0.2520
Complex manual: 0.8149
Complex matmul: 0.8099
I.e. almost a factor of five speedup.
