| 18 | ?S: This variable conditionally defines STAT_MACROS_BROKEN if some | |
| 19 | ?S: of the S_IS*() macros from <sys/stat.h> give false positive on | |

| 23 | ?C: This symbol, if defined, indicates that the S_IS*() stat macros | |
| 24 | ?C: such as S_ISBLK() give false positive and are thus unusable. | |
| 25 | ?C: Your best bet is then to supply your own set. | |
