As a related side question that I've been wondering myself for some time
already: what is the preferred way to compile numpy/scipy with those gcc
optimization flags? Afaik, numpy's setup.py is simply picking up the
flags that my distro's python was compiled with... Would the best way be
to recompile python myself? Or could I fine-tune the gcc options just
for numpy/scipy somehow?
Vincent.
