| 324 If we don't have Cyg_ErrNo, just use a cyg_int32 instead, to | |
| 325 make sure that the fields are still correct for the input | |
| 326 test vector. | |
| 327 In doTestVec(), before checking errno, check if we're | |
| 328 in IEEE mode (either compiled in or set at runtime) because if | |
| 329 so, and errno is set in the errno field of the input test | |
| 330 vector, then we have to skip this, since we can't validate the | |
| 331 output. | |
| 332 In all modes, if errno is set in the input test vector, don't | |
| 333 bother checking the actual values | |
