0.7 compilation fails

Hi Guys,

Slack 10.1, g++ 3.3.4

Validator.cpp:140: error: ambiguous overload for 'operator+=' in 's +=
   (+(+params)->XmlRpc::XmlRpcValue::operator[](0))->XmlRpc::XmlRpcValue::operator[](((+(+params)->XmlRpc::XmlRpcValue::operator[](0))->XmlRpc::XmlRpcValue::size()
   - 1))'

make[1]: *** [Validator] Error 1
make[1]: Leaving directory `/home/andrej/source/xmlrpc++0.7/test'

Any ideas how to fix this? :*)

Cheers,

I was able to get past that error by changing that line of code to call the string::append member instead of the operator+= which it is confused about.

i.e.

140:  s.append(params[0][params[0].size()-1]);

There seems to be other problems though -- is this project defunct?
