That's interesting. I didn't realize there was a gcc that didn't
support -m. This seems like an odd thing not to support, but whatever. :)

I've got a homegrown patch that basically removes a lot of the GNU-ness
from the configure to support Sun's compiler, but I don't think I had to remove
-m.... so even that won't help you.

Yes, please file a JIRA in HADOOP and attach the patch.
Thanks!
