Dynamic C 10.6 problems in RS232.lib

I wrote a code in Dynamic C 10.6 and ran it, it did connect with the board but it had an error. What’s the error, can anyone help me out? Thanks in advance! Below is the screenshot of the error.

Note that is just a warning message, not an error message. You can probably make it go away by explicitly defining those macros in your code.
