True, it only issues warning messages, but so many warning messages
are bothersome to read through when building a large system with lots
of class files. Plus, the quality of the generated native code is highly
dependent on the quality of the byte code that gcj starts with. It's quite
important to start with good byte code to finsh with a decent native
code module.
