MSP430 extended address bus

Posted by http://schneiderham.blogspot.co on June 11, 2010
I am trying to compile the MSP430 demo project with IAR. The MSP430F449 compiles with 1 warning. If I try a different MSP with extended address bus (20-bit) then I get a series of warnings,

Warning[408]: Only 16bit will be pushed to the stack. Use size specifier to avoid warning. .....

I figure this is because the stack size of this processor is now unsigned long instead of unsigned short as in the 449.

So If I redefine:
#define portSTACK_TYPEunsigned portSHORT
#define portSTACK_TYPEunsigned portLONG

and change the define:
#define portBYTE_ALIGNMENT2
#define portBYTE_ALIGNMENT4

I don't see any change. Does anyone have any experience with the MSP430 with extended address bus?

Thank you for your time,
