Colin Patrick McCabe commented on HADOOP-8569:
----------------------------------------------

On a related note, I have a bunch of patches to get native compilation working under OpenBSD that I really should submit at some point.

> In the native code, we should define _GNU_SOURCE and _LARGEFILE_SOURCE so that all of the functions on Linux are available.
> _LARGEFILE enables fseeko and ftello; _GNU_SOURCE enables a variety of Linux-specific functions from glibc, including sync_file_range.
