| | 14 | before including them, this header should be included to temporarily |
| | 15 | suppress the warnings and after this the header afterstd.h should be |
| | 16 | included to enable them back again. |
| | 17 | |
| | 18 | Note that there are intentionally no inclusion guards in this file, because |
| | 19 | it can be included several times. |
