| TODO: All the libomp source code uses pid_t type for storing the result of getpid(), it is good. |
| But often it printed as "%d", that is not good, because it ignores pid_t definition (may pid_t |
| be longer that int?). It seems all pid prints should be rewritten as |
| |
| printf( "%" KMP_UINT64_SPEC, (kmp_uint64) pid ); |

| printf( "%" KMP_UINT32_SPEC, (kmp_uint32) pid ); |
