Depends on the specific warnings.  Often the disables are needed at the 
call site instead or in addition.

I've also seen some warnings raised by template code that are 
essentially impossible to pragma away (without disabling for the entire 
translation unit) as they get attributed to the instantiation "line" 
outside of all user code.  Those are especially annoying.
