| 151 | * returns: |
| 152 | * |
| 153 | * - signal number in bits 0-6; |
| 154 | * - core dump flag in bit 7; |

| 157 | * Bits 0-7 are always zero for DJGPP, because it uses system(). |

| 161 | * the return code. Unfortunately the W* macros for DJGPP use |
| 162 | * a different format than Unixy wait does. So there's a mismatch |
| 163 | * and, say, WEXITSTATUS($?) will return bogus values. |
