Wt

Hello,

std::size_t myval(0);
Wt::WString::tr("mystring").arg(myval);

does not compile using macos. It seems that no suitable function can be found.

If I refer to http://fr.cppreference.com/w/cpp/string/basic_string/to_string, I think the following should be defined:

- unsigned

- unsigned long

• unsigned long long

However, we just have ::uint64_t and unsigned with the arg() function.
