You almost certainly don't want "arm_elf" either.

Yes.  If you have "-Drtems" then I think you get __rtems__ automatically.  But 
-Drtems is generally undesirable anyway because it pollutes the user's 
namespace.  So I suggest you remove that one and stick with just -D__rtems__.

Yup.  But that's just a stylistic issue.  I certainly wouldn't worry about it 
on the branch, though you might want to change to the new style on the trunk.
