Compiler Warning (level 1) C4142

benign redefinition of type

A type was redefined, but the redefinition had no effect on the code generated.

This warning commonly occurs in these cases:

• The return type of a member function of a derived class differed from the return type of the corresponding overridden member function.
  
  
• A type defined with the typedef command is redefined using different syntax. For example, the following code causes this warning when generating 16-bit code:

    typedef   unsigned int WORD; 
    typedef   unsigned short WORD;
  

This warning is informational.
