Hmm... it doesn't seem to be redundant on Mac OS X:

john$ gcj -o bar --main=TestAWT TestAWT.java
/usr/bin/ld: warning multiple definitions of symbol _sqrt
/usr/local/gcc_cvs/lib/gcc/powerpc-apple-darwin7.4.0/3.5.0/../../../ 
libgcj.dylib(libgcj.6.0.0.dylib-master.o) definition of _sqrt
/usr/lib/libm.dylib(sqrt970.o) definition of _sqrt

john$ ./bar
Exception in thread "main" java.awt.AWTError: Cannot load AWT toolkit:  
gnu.java.awt.peer.gtk.GtkToolkit
   <<No stacktrace available>>
Caused by: java.lang.ClassNotFoundException:  
gnu.java.awt.peer.gtk.GtkToolkit not found in [file:./, core:/]
   <<No stacktrace available>>

john$ export CLASSPATH=/usr/local/gcc_cvs/share/java/libgcj-3.5.0.jar

john$ ./bar
false
true
{i.e. it starts up and runs as it should.}
