There is a name conflict between std::bind and Poco::Data:Keywords::bind when using c++11 in gcc.

Code:
Poco::Data::Session session(...);
session << "somesql ?", bind(std::string("Text"));

Error:
error: cannot convert 'std::Bind_helper<false, std::basic_string&, const char (&)[1]>::type {aka std::Bindstd::basic_string<char(const char)>}' to 'Poco::Data::CopyBindingstd::basic_string' in return
