Mixed Language Makefile for Syslink example

Hi, I am currently using syslink_2_21_03_11 example 4, the exact file name is ex04_sharedregion.

This concerns the DSP portion of this example. I have made modifications to the Server.c file in order to implement additional code written in c++, so what I did is added extern "C" infront of all the originating C functions, and added the calls to my c++ functions and changed the filename to Server.cpp. Now the problem is, I don't know how to modify the makefile in order for this to compile. Here is the makefile (the only thing I changed is Server.c to Server.cpp):

#
