Yourself wrong. Bam.
You see that that is not useful to just claim it's wrong?

-m64 is the default on where it has been configured so. Just because
your shiny x86_64 install does that, does not mean it is universal.
Oftentimes RISCs, and sparc64 is usually one of these, defaults to
defaulting to 32, because 64 is slower there. Of course you can
compile a gcc that defaults to 64.
