There are two separate threads here, one about startup code ensuring
Supervisor mode and the other about creating an ARM build using CrossWorks.

The startup code being the code that executes to setup the C environment,
then calls main().  In this case it is called crt0.s, and is included in the
sample FreeRTOS project under the System Files folder (in the CrossWorks
Project Explorer window).

This code has to ensure the processor is in Supervisor mode when main() is
called.  CrossWorks makes this really easy - all you have to do is define
SUPERVISOR_START as a preprocessor macro.  If you look under menu option
Project->Properties->Preprocessor->Preprocessor Definitions you should see
how this is done.

If you are new to CrossWorks I suggest looking over the relevant manual
pages on Solutions, projects and configurations:
