 That didn't help, either.
gcc -msse2 -shared -fPIC -mpreferred-stack-boundary=2 -O2

 No need to wait - I'm using CVS version anyway due to bug #523612
If the fix will break GSL, GTK, Cairo or OpenGL bindings, I'll let you know.
Thanks for the fix and advice! That's the power of the open source!

And by the way: I suspect I'm doing SSE totally wrong, but it's still
two times faster than typed CL or C without _mm_sqrt_pd (the last two
being on par).
