Why am I unable to use blocks from the DSP Blockset with the Embedded Target for MPC555 1.1 (R13SP1)?

When I try to compile a model that contains a block from the DSP Blockset, I receive the following error in the MATLAB Command Window (using DIAB Compiler):

 c:\matlab6p5p1\toolbox\rtw\dspblks\c\dspburg/burg_a_c_rt.c -o burg_a_c_rt.o
