PUGIXML_HAS_LONG_LONG define enables support for long long type in pugixml. This define is automatically enabled if your platform is known to have long long support (i.e. has C++11 support or uses a reasonably modern version of a known compiler); if pugixml does not recognize that your platform supports long long but in fact it does, you can enable the define manually.
PUGIXML_HAS_STRING_VIEW define enables function overloads that accept std::basic_string_view arguments. This define is automatically enabled if built targeting c++17 or later AND if PUGIXML_STRING_VIEW is also defined. The requirement to additionally define PUGIXML_STRING_VIEW will be retired in a future version.
