Hi Jerry, two quick comments.

I wanted to ask how are you testing the ongoing work: I remember you had 
a script comparing printf to the inserters and that we still had some 
minor problems (proably false alarms) in corner cases... I would be 
happy to run something similar on a few 64-bit architectures but maybe I 
will not be really able to do that during the next 1 & half week or so. 
Let's keep in touch.

Another unrelated comment: are you taking into account in the design 
that bug with grouping & zero precision (no decimal point, anyway) that 
I mentioned some time ago? Basically, we look for the decimal point and 
we group everything to its left: if we don't find it, we group also the 
exponential part, if present! Fixing it in the current framework its 
feasible but very ugly, and I was wondering whether we can arrange for 
the new framework to make it easier...

Paolo.
