Question about gcj 64 bit compilation.

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?
