 For reasons I don't understand it can't cope with partial specializations
 for both std::basic_string and boost::container::basic_string.  Commenting
 out the latter fixes the issue BTW (there are quite a few traits class
 specialisations that need to be commented out though!).

 Not sure if this is a general STLPort issue (don't see why it should be),
 or a specific compiler issue.
