/* These following sections create versioned symbols for the

   libgomp ``versions'' its symbols (OMP_1.0, OMP_2.0, OMP_3.0, ...) while also
   retaining the default version which libomp uses: VERSION (defined in
   exports_so.txt). If you want to see the versioned symbols for libgomp.so.1
   then just type:
 
   objdump -T /path/to/libgomp.so.1 | grep omp_
 
   Example:
   Step 1) Create __kmp_api_omp_set_num_threads_10_alias which is alias of
     __kmp_api_omp_set_num_threads
   Step 2) Set __kmp_api_omp_set_num_threads_10_alias to version:
     omp_set_num_threads@OMP_1.0
   Step 2B) Set __kmp_api_omp_set_num_threads to default version:
