Subject: <ranges> error: requires clause differs in template redeclaration
Date: Mon, 13 Feb 2023 12:14:35 +0100	[thread overview]
Message-ID: <ef2a3bb5-86aa-8c6a-a6d1-8a508ca2c690@redhat.com> (raw)

I just noticed that Clang -std=c++2b complains (and I assume rightly so) 
about <ranges>

that had been added with

"libstdc++: Implement ranges::repeat_view from P2474R2", respectively.
