Unfortunately, "pow" isn't yet recognized as a GCC built-in function.
Both "exp" and "log" are recent additions, and the original patch to
implement them as inline 387 intrinsics is still under revision.
Once again, not a show-stopper. Given that Mark has stated that we've
officially passed the stage 3 cut-off, we can wait to add support for
"pow" and friends in October after 3.3 has branched.
Nice set of transformations, though.
