Why am I getting Unresolved External ErrorDesc() at link time
 This is from an old MrDebug sample Error System
──────────────────────────────────────────────────────────────────────────────

 If you are getting this message when using MrDebug 1.1, then you are linking
 an error system design for use with a previous version of MrDebug.

 ErrorDesc() was renamed to MrDErrorDesc() in MrDebug 1.1

 Solution: Change to the new MrDebug error system - this will ensure that
           there are no conflicts in function names.
