i've not done any real-world profiling but doesn't enable-final speed 
up not only compiles but also builds due to the fact that gcc can inline 
more relevant code that otherwise?, probably decreases object size also.
but if its enough difference to be seen, i'm not sure.

gcc (well, iirc ada does but not c++) afaik doesn't yet have interfile 
inlining/optimisations yet, or does HEAD have it now?
