I am compiling Java source code in Mandriva 2011 64 bit,
and default mode runs happily.
The -m32 mode behaves as expected.
However, when I try
gcj Test.java --main=Test -m64 -o Test.bin
I get the error:
jc1: sorry, unimplemented: 64-bit mode not compiled in
If my linux is 64 bit and if I omit -m64 and let it proceed,
will gcj compile into 64 bit by default?

This error means that your gcj compiler was built without support for
x86 64-bit mode.
