I am using mcpp to scan through the source files to find whichever defines available and then just enable those lines of code from source depending upon the defines. This is working fine using mcpp. But for some other purposes, I need few of the defines to be intact without changed by mcpp, because those defines I will be using for some other processes I do in the code. Is it possible in mcpp. Please advise me how to do ?
