To build the binary, run the build.bat file:
Either double click on the file, or
Open a command window/prompt in the directory containing these files.  Type build and hit enter.  

To build in Code Composer:
Create a new Code Composer Studio project using a directory containing these files (or copy them into a project).  
DSP_batch_linker.cmd should be ignored.  It can either be deleted from the project folder, or you can right click the file, select Properties, and check the "Exclude resource from build" box under CCS Build options.
The following line must be added as a post-build step to a CCS project.  In CCSv5.1, select Project>Properties, and under "CCS Build", add the line into the "Command:" box of the "Post-Build steps"
    "${CG_TOOL_ROOT}/bin/hex6x.exe" -b -o "${BuildArtifactFileBaseName}.bin" "${BuildArtifactFileName}"

When creating the binary output, there should be four entries from the binary build process:
Translating to Binary format...
   "DSP.out"   ==> .text:_c_int00
   "DSP.out"   ==> .text
   "DSP.out"   ==> .cinit
   "DSP.out"   ==> .const
