Thanks, that works fine.  (The code I posted had the wrong size for a, though.)
I was searching in the gcc --help -v output before for stuff with sse, but
that didn't find the -mfpmath option, since there is no description of its
possible parameters, so I though my gcc installation didn't support sse math.
