Why do you think it'd be more computationally demanding? Each header file is 
compiled exactly one with --enable-final, and not dozens upon dozens of 
times. And I don't think gcc's inliner is active enough to pull in much stuff 
from the non-inline methods. Hmm, I haven't compared this much with gcc-3.2, 
though.
