Subject: Fix FreeBSD/OpenBSD/NetBSD compiler warnings in get_default_gateway()
X-Git-Tag: v2.3-alpha1~60
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=93626f2cf71b4803aa1248a928bfc1ac8c9da18b;p=thirdparty%2Fopenvpn.git

Fix FreeBSD/OpenBSD/NetBSD compiler warnings in get_default_gateway()

On these platforms (including DragonFly), get_default_gateway() would in some
cases return false.  As get_default_gateway() is defined as a void function, and
none of the callers expect a return value -> just return without any value.
