define of DBUS_SYSTEM_CONFIG_FILE ?

["YAO Ye" <yesiryao@xxxxxx>]

hi, bluez users:
     for some reason, i need to change the define of DBUS_SYSTEM_CONFIG_FILE, but i can't find where it is defined in the source code of bluez/dbus/dbus-glib, etc.

could you tell me some info abuout DBUS_SYSTEM_CONFIG_FILE ?
thanks a lot!

//following is the source code in dbus/dbus/dbus-sysdeps-unix.c
//DBUS_SYSTEM_CONFIG_FILE default set to "pxalinux/rel/host/etc/dbus-1/system.conf"
dbus_bool_t _dbus_append_system_config_file (DBusString *str)
{
      return _dbus_string_append (str, DBUS_SYSTEM_CONFIG_FILE);
