In Clang 16, we implemented the ability to add a label at the end of a compound statement. These changes complete the implementation by allowing a label to be followed by a declaration in C. Note, this seems to have fixed an issue with some OpenMP stand-alone directives not being properly diagnosed as per: https://www.openmp.org/spec-html/5.1/openmpsu19.html#x34-330002.1.3 (The same requirement exists in OpenMP 5.2 as well.)
