If we don't see C++ support coming, we could use -Wc23-labels. Otherwise -Wflexible-labels, -Wunrestricted-labels, -Wenhanced-labels … Or separate options: -Wend-labels, -Wdeclaration-labels. But I don't think anyone would want to treat those two cases differently. > Note clang just uses Wc++23-extensions/Wc23-extensions (which is > similar to GCC's Wc11-c23-compat) and does not seem to have another > option to enable/disable this specific one. Indeed, I couldn't find a more specific option, either. Thanks, Florian
