You can either fix this by yourself by merely rewriting the skeleton  
file using a std::string instead, or persuading Akim Demaille doing  
it in the C++ parser rewrite he is working on now.

As for the first approach, you might check the way I did it in the  
Bison_Patches archive, in the thread "FYI: lalr1.cc: Remove the  
traits", 19 September 2005, where I posted my skeleton file.
