The blanket warning for OpenMP support was removed in https://github.com/llvm/llvm-project/pull/144915. This specific warning is for versions above version 4.0 (or is it for version 5 and above?). The work for these versions are not complete as seen in https://flang.llvm.org/docs/OpenMPSupport.html.

I think we should probably update the support table for 4.5, 5.*, 6 and then decide to remove the warning. Probably also update the status of OpenMP offloading tests in https://discourse.llvm.org/t/openmp-offload-fortran-tests-pass-with-flang-new/78919/8. And then make a collective decision, if that is OK for @kparzysz @tblah @skatrak.
