What's the state of efforts to reduce GCJ's footprint?

When I was working on this option, I did build libgcj this way by 
hacking libgcj.spec.in before building. The result was runnable, it 
should work under almost all conditions. IIRC, this reduce the size of 
libgcj by about 5% - 7%. Read the documentation for 
-freduced-reflection for more details.
I am thinking of adding a configure option so that this build type can 
be selected without hacking the sources.

What the messages says is true!. -freduced-reflection only affects code 
generation of java classes, thus it is not valid in other contexts.
