--- Comment #21 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-07-22 15:31:15 UTC --- Hum (Jason and Daniel, in particular) I'm wondering if the issue could fall under http://lwg.github.com/issues/lwg-active.html#2013 but then, we would be able to assume / do it only for glibc on which we have control?!? I have no idea if the implementations in the various libc out there all satisfy the prerequisites for a function to be marked constexpr. Do you see my point? Or Jason you mean something else entirely?
