So, I guess this is fine now and NetBSD is broken.
It was undefined in POSIX.1-2001: https://pubs.opengroup.org/onlinepubs/000095399/functions/fflush.html But well-defined in POSIX.1-2008: https://pubs.opengroup.org/onlinepubs/9699919799/functions/fflush.html So "recently" is at least 17 years ago :-)
