gcj onLinux, 32 and 64 bit executables.

[Me Myself and I]

If I successfully compile a Test.java program with gcj Test.java --main=Test -o Test.bin
on 64 bit linux, I then have a 64 bit Linux exectuable.

If I do similar on 32 bit Linux, I have a 32 bit Linux exectable.

If I am running 64 bit Linux, is there a way to use gcj on this to get a 32 bit Linux bin,
what should I do for this, where should I look, and can anyone give me any simple,
practical instructions on how to set it up?
