Why do I receive linking error when I try to create a C++ stand-alone external application in the Microsoft Visual C/C++ IDE?

Why do I receive linking error when I try to create a C++ stand-alone external application in the Microsoft Visual C/C++ IDE 5.0 or 6.0 with the MATLAB C++ Math Library?

Here are the errors I am receiving:

 LINK : warning LNK4098: defaultlib "MSVCRT" conflicts with use of other libs; 

    use /NODEFAULTLIB:library

 .\ex1.exe : fatal error LNK1169: one or more multiply defined symbols found

 Error executing link.exe.

To resolve the problem please change the project settings to build a Multithreaded DLL in the Runtime Library. You can do this by:

1. Selecting Project from the main menu

2. Selecting Settings

3. Clicking on C/C++ Tab

4. Selecting Code Generation in the Category pulldown menu

5. In the Runtime Library field selecting Multithreaded DLL ( "Debug Multithreaded DLL" will not work)

6. Clicking OK

7. Rebuilding the .exe file
