I tried that. It doesn't work.

  ➜  cat test_omp_null_allocator.c
  extern int printf(const char *, ...);
  typedef enum omp_allocator_handle_t {
    omp_null_allocator = 0UL,
    omp_default_mem_alloc = 1UL,

    omp_const_mem_alloc = 3UL,

    omp_cgroup_mem_alloc = 6UL,
    omp_pteam_mem_alloc = 7UL,
    omp_thread_mem_alloc = 8UL,
    llvm_omp_target_host_mem_alloc = 100UL,
    llvm_omp_target_shared_mem_alloc = 101UL,
    llvm_omp_target_device_mem_alloc = 102UL,
    KMP_ALLOCATOR_MAX_HANDLE = 18446744073709551615UL
  } omp_allocator_handle_t;
  int main(int argc, char *argv[]) {
    printf("sizeof(omp_allocator_handle_t)=%zu, sizeof(omp_null_allocator)=%zu\n",
           sizeof(omp_allocator_handle_t), sizeof(omp_null_allocator));
    return 0;
  ➜  clang test_omp_null_allocator.c -o test_omp_null_allocator
  ➜  ./test_omp_null_allocator
  sizeof(omp_allocator_handle_t)=8, sizeof(omp_null_allocator)=4
