        <pre>Not sure if this code has become illegal with the newer OpenMP versions or if
it's a bug.
But the information should be conveyed in the error, not in a warning.

I usually have to disable -Wignored-pragmas in cl mode because of the many
msvc-specific pragmas in some codebases.
In general it would be nice to have a separate category for OpenMP or make it
errors right away.

{
    int size() { return 1; }
};

    A target;

    {
