Err. I think you mean the rumors of V3 working with newlib have been 
greatly exaggerated. As a matter of fact, it's been working since about Feb.
I did a cross x86-x-powerpc-elf this Sunday, as a matter of fact, and it 
worked well.

I'll fix this.

... this has been my experience as well. Nice to see it confirmed.
