Perhaps, but

boost::function<void, int> f(g); // 1

and

g(1); // 2

are exactly equivalent in terms of the compiler warnings that they produce;
so if an user is likely to ignore the warning in (1) he/she will also ignore
it in (2).

Yes, you are right, however GCC doesn't warn about (2), either.

I used to use

#if defined(_MSC_VER) && !defined(__ICL)
#pragma warning(disable: 4786) // identifier truncated in debug info
#pragma warning(disable: 4710) // function not inlined
#pragma warning(disable: 4711) // function selected for automatic inline
expansion
#pragma warning(disable: 4514) // unreferenced inline removed
#endif

#ifdef _MSC_VER
#pragma warning(push, 3)
#endif

#include <iostream>

#ifdef _MSC_VER
#pragma warning(pop)
#endif

The new VC 7 library is relatively clean at level 4 (at last!)
