Using a local prototype for fallocate instead of the fcntl.h header meant that the redirect triggered by -D_FILE_OFFSET_BITS=64 was not triggered. The prototypes in feature_detection_stdio.h should only be used by functions in setup_common.py. If they are used by the feature discovery code they might trigger false positives.

Closing this, we’ll review the PR to main and if that gets merged do a backport afterwards per our normal process. |

This is the backport of #25631 which was merged after triage discussion. |
