LWIP will not compile with FreeRTOS

[MattJCole]

I am Using S32 Design Studio for Power Architecture Version 2.1 with the MPC5748G_178 processor.

When I have the FreeRTOS and TCPIP module in the project and try to call the tcpip_init function I get the following compiler errors

Found the problem the FreeRTOS defaults to the wrong number of "Thread Local storage Pointers". By default it is set to 0. When set to 0 those function are not defined
