Actually, we can enable it if either `-fopenmp-version=52` or > `-fopenmp-extensions` is used, depends if we want to add a switch for > non-standard OpenMP extensions. If OpenMP 5.2 is on, we can just ignore > `-f[no]-openmp-extensions`. Thoughts? Consider that, if `-fopenmp-version=52` is sufficient to enable all extensions using the `ompx_` prefix, then all such extensions will be enabled by default once OpenMP 5.2 is the default. At that point, won't it be strange that standard OpenMP 5.3 or 6.0 features will be disabled by default while some features appearing in no standard will be enabled by default? By that logic, it seems `-fopenmp-version=52` shouldn't be sufficient to enable extensions. However, it seems overkill to have to specify both `-fopenmp-version=52` and `-fopenmp-extensions`. I think `-fopenmp-extensions` is a clear enough request to enable the `ompx_` prefix regardless of the OpenMP version.
