name-lookup (such as gcc >= 3.4). The fix for this is to tell the
compiler what symbols to use withlines like: using MultiArg<T>::_name;
This is now done and everything compiles fine. Since I'm not sure
about the support for things like using MultiArg<T>::_name; on all
compilers it is ifdef:ed away by default. To get 2 stage name-lookup
to work you have to add -DTWO_STAGE_NAME_LOOKUP to your CXXFLAGS
before running configure.
