When trying this, it (still) works as host fallback but offloading gives:

  219 |   OMPTO (a);
for-2.h:219:1: error: variable '.omp_data_kinds.116' has been referenced in
offloaded code but hasn't been marked to be included in the offloaded code

  222 |   OMPFROM (a);
for-2.h:222:1: error: variable '.omp_data_sizes.118' has been referenced in
offloaded code but hasn't been marked to be included in the offloaded code

(And likewise for additional OMPTO/OMPFROM.)
