OK - let's strike that part. (I have to admit that I do not really understand
the fine print of "composite constructs" - contrary to combined constructs.)


Nonetheless, the following C/C++ issue remains for this PR:

    #pragma omp for simd ordered(1)

is now in OpenMP 5.2 permitted, but currently reject.

[And likewise: 'doaccross' as synonym of 'depend' w/ sink/source.]
