Wrong C++ version check for span_HAVE_NORETURN? #83
Description
Compiling as C++11, I see:
/home/smarchi/src/babeltrace/src/cpp-common/vendor/span-lite/span.hpp:831:1: error: function 'throw_out_of_range' could be declared with attribute 'noreturn' [-Werror,-Wmissing-noreturn]
831 | {
| ^
/home/smarchi/src/babeltrace/src/cpp-common/vendor/span-lite/span.hpp:854:1: error: function 'report_contract_violation' could be declared with attribute 'noreturn' [-Werror,-Wmissing-noreturn]
854 | {
| ^
The definition of span_HAVE_NORETURN is:
#define span_HAVE_NORETURN span_CPP17_000
cppreference says it's available in C++11:
https://en.cppreference.com/w/cpp/language/attributes/noreturn
So I guess the definition of span_HAVE_RETURN should be span_CPP11_OR_GREATER or one of the span_CPP11_* ones. I have no idea about the support of MSVC for this, unfortunately.
