X-Git-Tag: v6.8~31
X-Git-Url: https://git.armaanb.net/atreides/tree/README.md?p=opendoas.git;a=commitdiff_plain;h=b1ae418af40289ea4f40449a819df26ee3bdd399

Fallback definition for HOST_NAME_MAX.

On some platforms(NetBSD) where HOST_NAME_MAX is not defined,
provide a fallback definition to _POSIX_HOST_NAME_MAX.
