From b9420c3bfc2a8b9d35d0c8e5f6849007c2bc21fa Mon Sep 17 00:00:00 2001
From: Darik Horn <dajhorn@vanadac.com>
Date: Mon, 14 Apr 2014 13:22:24 -0400
Subject: [PATCH] Use FHS installation directories.
Install to `/usr/sbin`, `/usr/lib`, and `/var/lib` according to the Linux
filesystem hierarchy standard if SoftEther is built through autotools.
In a managed installation, the FHS stipulates that the application must
accomodate a read-only installation path. This requires a new `GetStateDir`
function that substitues `GetExeDir` in some parts of the code.
Taken from Github at
https://github.com/dajhorn/SoftEtherVPN/commit/b9420c3bfc2a8b9d35d0c8e5f6849007c2bc21fa.
