Agreed - and previously suggested to the author. |Apart from that marginal gain, the point | is whether we want to support the insane VC 7.1 warning level 4. I am strongly in favour of supporting 8.0 warning level 4. It provides ***some*** useful warnings, as well as some less helpful ones. Code that is warning free is a higher quality even if the warnings are supressed because it shows the issues have been considered. Some groups enforce 'strict' warning level as a matter of policy and I think Boost should respect this decision, even if considered insane by some.
