[PIC] Problem while compiling the code in c18 standard evaluation compiler from microchip

I am using mplab v8.76 and i downloaded the c18 compiler from microchip. While compiling the code it shows the following warning. Initially, i tried led blink code for that it didnt show any warning or error. It gets compiled.
