'jikes' should generate code similar to that generated by 'javac'.
(It's just a compiler, not an optimizer or replacement JVM.)

All 'jikes' does is replace the Java-coded compiler with one written
in C++ which, in my opinion, is a good thing, for at least the short
term.  When you're running a compiler, you don't really want to pay
the 2 second price of starting up a JVM only to spend half a second
compiling a single Java class.
