using std::string ignored with latest version

[peremato]

Hi Philippe. I have tried with WrapIt.jl and I get the problem that the statement using std::string is ignored when generating the wrapper code. The following example does not generate the wrapper for the constructor nor the method str.

#include <string>

using std::string;
class MyClass {
public:
    MyClass(const string& str) : m_str(str) {}
    string str() const { return m_str; }
private:
    string m_str;
};

These are log messages with v=5

Note: the issue was present when using clang versions above 13.

Commit e68c127 fixes the issue and clang releases above 13 can now be used.
