This code at least works:

     string directory_path(argv[1]);
     path p(directory_path);
     ostringstream component;
     string lastComponent;

     for (path::iterator it = p.begin(); it != p.end(); it++) {
         component.str("");    // Hack, to be replaced by better way
         component << *it;     // to grab `*it' in a string
         lastComponent = component.str();
     }

     lastComponent = lastComponent.substr(1, lastComponent.size()-2);

According to the documentation examples, the item pointed to by `*it' is 
of the following type:

path::iterator::value_type is path::string_type, and iteration treats 
path as a container of filenames.

I tried to capture `*it' in a string and in a string_type but the 
compiler does not like the '=' operator.

TIA,
