As far as I know, they are not something you should be nervous about.

Some time ago I found (I do not remember where) a list of warnings that 
are not helpful at all but can be generated when compiling modern libs.
The list of these warnings and the macros I use to shut them up (all 
this is in the header file that I include where needed) are:

// these are the meaningless warnings:
// 4097 4127 4250 4251 4275 4284 4290 4291 4355 4505 4511 4512 4514 4554 
4706 4710 4786 4800

// for VC++6: _MSC_VER == 1200

# if defined _MSC_VER
#   if (_MSC_VER == 1200)
#     pragma warning (disable : 4097 4251 4275 4284 4355 4511 4512 4514 
4786)
#   endif
# endif

// for VC++7.1: _MSC_VER == 1310

# if defined _MSC_VER
#   if (_MSC_VER >= 1300)
#     pragma warning (disable : 4251)
#   endif
# endif

I disable only those warnings that were appearing in my compilations 
(so, as you can see, VC++7.1 generates far less warnings than VC++6) and 
*only* those from the list above. You may need to modify the disable lists.

At least I can show the "0 warnings" message to my boss. ;-)
