I was hoping to avoid 13.x since there seems to be a noexcept bug in that release series, though some other testing seems to suggest this is transient (and also I wanted to align with what Oracle uses, which is 14.x). I guess I can roll back to 13.x if that is really needed > P0283R2: Ignoring unsupported non-standard attributes It's probably important to note that MSVC takes this to mean that unknown attributes don't have an effect, and still warns for them when warning C5030 is enabled (which is by default in our make system): https://developercommunity.visualstudio.com/t/c-warning-c5030-generated-for-attribute-within-a-n/138429 ------------- PR Comment: https://git.openjdk.org/jdk/pull/14988#issuecomment-1886575743
