[iiwusynth-devel] Compiler flags

[M. Nentwig]

One more thing:

I found a flag -ffast-math, that speeds up math operations by
sacrificing full IEEE compatibility. Tested it on a five-line program
with sin() and cos(), it really helped a bit.
Also, the gcc manual says, that -funroll-all-loops may be slower than
-funroll-loops?!
