In an email exchange with P.J. Plaugher a couple of years back on his 
Dinkumware distribution (the one used in MSVC 5 and 6), he told me 
that many of his headers re-enable warnings at the bottom rather than 
using a "push/pop" method for temporarily disabling things to suit a 
particular header.

The net effect is that at the bottom of <map> or <list>, there is a 
hardwired #pragma warning (3:4786) which resets 4786's to level 3, no 
matter what you try to do.

He considered this to be a bug, he fixed this in his standalone C++ 
library distribution, but told me that Microsoft declined to fix this 
in the version which ships with 6.0.

My personal workaround has been to do the following:

#pragma warning(disable:4786)

#include <map>
#include <string>
// etc.

#pragma warning(disable:4786)

This cuts down on the noise considerably.
