| OK, before I clean up the patch, I'll post an example. For this code:
| 
| ----------------------------------------------
| #include <map>
| #include <vector>
| #include <string>
| 
| std::map<std::string, std::vector<int> > m;
| 
| void bar(void)
| {
|   std::vector<int> k;
|   m.insert(std::make_pair(0, k));
| }
| ----------------------------------------------
| 
| I get this:
| 
| <path>/stl_pair.h: In constructor 'std::pair<_T1, _T2>::pair(const 
| std::pair<_U1, _U2>&) [with _U1 = int, _U2 = std::vector<int>, _T1 = const 
| std::string, _T2 = std::vector<int>]':
| test3.cc:10:   instantiated from here
| <path>/stl_pair.h:90: error: invalid conversion from 'const int' to 'const 
| char*'
| <path>/stl_pair.h:90: error:   initializing argument 1 
| of 'std::basic_string<_CharT, _Traits, _Alloc>::basic_string(const _CharT*, 
| const _Alloc&) [with _CharT = char]'
| 
| (I manually edited '<path>')
| Without my patch, I get this:

That is  fair improvement.  I realize we don't retain std::string in
the last diagnostic, but we don't need to do that before you check-in
your patch -- that is a whole project in itself.
