Proposed patch



I'm now testing this patch.  It fixes the overlapping reg negdi problem. 

There's a code size increase in CSiBE:



linux-2.4.23-pre3-testplatform

  lib/vsprintf     4776 -> 4820         +44 / +0.921273 %



I haven't checked the details of this case, but I guess this is the price of

correct code ;)
