Yes, very much so. You'll get better performance than with the
workaround I suggested (disabling inline asm). I need to run a few
tests with gcc 4, but eventually will fix the problem along these lines.

That wil be costly in performance, especially if -O0 is applied to the
whole OCaml runtime system (not just otherlibs/num).
