Comment:
> `/usr/include/sys/unistd.h` just contains `#include <unistd.h>` on glibc, so I think there is no need to put that behind an ifdef, we can just include it everywhere. @kruceter could you send that patch upstream if they don't have it yet?

Could you use <https://github.com/sandialabs/seacas/pull/348.patch>?
