I am a newbe to the C/C++ Development System.  I downloaded the C/C++ Development System a couple of days ago.  In following the directions for Lesson 1: Create the DOS Application, when I did the Rebuild (called for in the instructions), I got an error:
Error: c:\dm\lib\sds.lib(cinit) : Previous Definition Different : __Exit.

The instructions say nothing about this.

Is there something missing in the instructions for Lesson 1?
