GCC 5 -Wall issues warning about clang::fallthrough attribute placement in string_view header #42
Description
When building libbsoncxx against core HEAD with -Wall, I'm getting lots of warnings about the use of the clang::fallthrough attribute in the new string_view header:
src/bsoncxx/third_party/EP_mnmlstc_core-prefix/src/EP_mnmlstc_core/include/core/string_view.hpp:100:55: warning: attributes at the beginning of statement are ignored [-Wattributes]
case 2: hash ^= ::std::uint64_t(data[1]) << 8; [[clang::fallthrough]];
Easy enough to work around by adding -Wno-attribute but that is not ideal.
