You can also be a compiler writer:

For what is worth, I understand the point by Andrew that without -fopenmp, the
#pragmas are effectively ignored, thus the warning seems useful. Perhaps it
would be more useful a specific -Wopenmp-pragmas  that says:

 warning: ignoring '#pragma omp parallel' without '-fopenmp' [-Wopenmp-pragmas]

But it seems more important to fix PR53431, if someone has time for that.

The zero-column ":0" in the diagnostic is also a bug.
