This macro definition means that the following program is executed as soon as the DEBUG_IR_RCV is defined. Whether the defined DEBUG_IR_RCV is 0 or not 0.

#if DEBUG_IR_RCV

Start_capture ()//init infrared wave capture
}

#endif DEBUG_IR_RCV macro definition must be not 0 to perform the following program
