Do you mean if my application includes "string.h" and some other library header files include "string" or "CString" then there would be a conflict?

Or is it because there are multiple includes of the same header file (i.e. string.h)?

Would it make a difference to dynamically link my application to the libraries rather than statically linking to the .libs?
