 FYI, probably no serious gcj users use this version.  It is way too
 old.
 
 Setting a breakpoint on a class' main hasn't worked for me for a long
 time.  Naturally, I'm always using a fairly recent gcj.  In this
 example, I'm using the appended code, gcj 3.3, and a fairly recent
 (less than a month old) cvs trunk gdb.

 (gdb) b HelloWorld.main
 the class HelloWorld does not have any method named main
 Hint: try 'HelloWorld.main<TAB> or 'HelloWorld.main<ESC-?>
 (Note leading single quote.)
 
 
 In the past I had some formula for making this work (I brought it up
 on the gdb list once last year), but I've since forgotten it.  I
 couldn't figure out how to get a breakpoint set there.
