This code compiles under MaxonC++ V1.1. If you use another
compiler you will have to make some adjustments so that the
two child tasks will work correctly. You might probably have
to turn off stack checking and use the __interrupt or
__saveds keywords at the appropriate places. You might
also have to change some include-filenames, i.e. <clib/...>
to <proto/...>

Have fun,
