large integer implicitly truncated to unsigned type

I have the following declaration in my program: -
#define PORT_MASK       0x100E1011UL
but when I compile it I get the warning: -
../example/src/gpio.c:42:25: warning: large integer implicitly truncated to unsigned type [-Woverflow]
I thought that UL declared a variable as Long and unsigned. Why do I get this warning?

Thanks for the help. Yes, I am using LPCOpen with the LPC824. I changed the declaration in the function parameter list and the warning has gone away.

Are you using this with LPCOpen for LPC800?

The error occurs when the constant is used as a parameter to Chip_GPIO_SetPortDIROutput() (some others have the same mistake). The "mask" parameter there is declared as uint8_t while it should in fact be uint32_t.

There is nothing's no wrong with your #define, and the compiler is not complaining about it. You will have to show us how you are using it (I.e. The line causing the error) for us to be able to help you.
