extern lhost_name after 4.22a patch

Hello.

We are following this example from Keil on how to configure the local host name of a system running on top of TCPNet.

http://www.keil.com/support/man/docs/rlarm/rlarm_tn_runtimecfg.htm

However, after the latest patch (4.22a) we get a linker error that lhost_name is an unknown symbol.

Did that global change names or is there a different way of configuring the host name now?

thanks
