Recreate Example001 from FreeRTOS manual

[lpcware]

Content originally posted in LPCWare by mwoodmansee on Mon Jul 29 18:41:42 MST 2013
I am trying to learn about the LPC1769 and am rewriting the examples used in Richard Barry's FreeRTOS manual.  When I compile a retyped version of Example01 called example01_rework I get the following compilation dump. 

Please provide your thoughts.

I think this FAQ from Code Red will help.
