--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It works properly if you use -fopenmp during preprocessing (or compilation).
Without -fopenmp, the pragmas aren't recognized.
In your use case, are you preprocessing separately without -fopenmp and then
compiling with -fopenmp? If so, why?
