I probably missed this one because in DWARF2, which is what i'm almost always using, unless we hit hash table collisions, which we almost never do (you'd need a *lot* of type names), == should be sufficient to compare type names when dealing with C++.
You do realize, of course, that the fact that it isn't  means you are duplicating info when reading in STABS/DBX/whatever debug format you are using,  that you shouldn't be.

Feel free to apply them.
