I can understand using old versions of a library with old projects, but 
why aren't you using the current version of MySQL++ with your new 
project at least?

Make sure the link settings are the same between your new program and 
the old one.  You might be attempting to link to the library twice, for 
example.  The current version of MySQL++ has good, detailed instructions 
at the bottom of README.vc for the settings that you need to check.
