   We have done it for individual warnings: Activate, fix for a few hours,   
   check-in; activate next, fix for a few hours, check-in; ...   
      
   And I mean *hours* per most warnings, because there's *always* the odd   
   case or two, where you have to dig deeper to decide about a warning.   
      
   For us, doing this for *all* W4 warnings simply didn't seem economically   
   feasible.

   And what are you doing about them? I mean, every odd file includes a   
   boost header! Developers will simply drown in warnings.   
      
   IMHO, from a build system POV, it should be possible to activate /   
   deactivate warnings not based on compilation unit, but based on files.   
   (So that a boost header file "never" generates a warning, and a on-site   
   developer file will have all warnings activated.) Well, wishful thinking   
   I guess.
