I found a way around it, but really is kinda poor one.

Код:

#if defined _INC_MACRO
    #endinput
#endif

#if !defined _INC_MACRO
printf();
#endif

#define _INC_MACRO

Wrapping the code within an #if statement it seems to work no matter how many times you include it. I don't know if you'll use it or will still to try and find a better solution.
