This patch is about the OpenMP 5.{1,2} implementation status.

For omp/ompx/omx, I think it was a bit misleading. omp/ompx (and omx)
are reserved namespaces; for 'omp' nothing needs to be done (either
already implemented or not), while for 'ompx'/'omx' (vendor extension),
the note + footnote tries to describe what happens. – I hope the revised
wording is clearer.

The other change is about two OpenMP 5.1 items; the first one seems to
get used in some code – 'begin declare target' is essentially the same
as 'declare target' ... 'end declare target' but additionally permits
clauses.

And the second new item: I think it was regarded as bug fix, but I
personally read it rather as change. The question is as what to read it
and how to handle it? Initially I wrote and thought of it as deprecation
of the previous syntax, i.e. warning but only once the OpenMP version
has been bumped to 5.2's. I now think we could diagnose it earlier – IMO
a warning would be sufficient, but it could also be read it such that an
error is required. – Thoughts about this item + what to implement?
