As discussed in the thread
   Re: [wwwdocs] gcc-13/changes.html + projects/gomp/: OpenMP update
   https://gcc.gnu.org/pipermail/gcc-patches/2023-January/610324.html
in https://gcc.gnu.org/PR107424 and the thread starting at
   OpenMP/Fortran: Partially fix non-rect loop nests [PR107424]
   https://gcc.gnu.org/pipermail/gcc-patches/2023-January/610240.html
the Fortrans support is still incomplete.

As suggested in the wwwdocs thread (see link), the implementation status
for Fortran needs to be 'P'.

(Short version of the issue: currently, there are many issues with
non-rectangular loop nests; the nearly ready patches will fix those
for stride == -1 and 1. Ideas exist for other strides, but this may
take a few more days to get resolved.)
