If the Java code is restricted enough then I think gcj will be as good
as C.

For best performance I think the code would have to:

* Not make static or final ("nonvirtual") method calls
  (These induce overhead relative to C++)
* Not use arrays
  (C++ does check bounds)
* Not "look like" it might throw an exception (this prevents
  reordering code)

There may be other restrictions that I can't think of.  These are
pretty restrictive, but the Math code might satisfy them.  I haven't
looked.
