Thanks for hunting that down. ]also dont need the -fPIC ]options. so I removed them too. static lib after all. Isn't this getting statically linked into a dynamic lib?

I had a look at the assembly ]produced and its quite inefficient at optimising the registers (gcc3.3.4). ]Id keep the older macros for now for performance reasons. Yep. But icc and newer gcc's like them. And those compilers may even clobber the old intrinsics in certain situations. -- Daniel
