disable overlay warning for specific functions

I have four functions that the linker gives me the warning:

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?UART_RX_ISR_STUB?ISR

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?TIMER0_ISR_STUB?ISR

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?TIMER2_ISR_STUB?ISR

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?ASDC0_ISR_STUB?ISR

These functions are not called within my application project. They *ARE* called from the bootloader project via a function pointer. Both projects are in non-overlapped CODE memory.

So how do I turn off these warnings for these segments/functions only?

I absolutely want the compiler to warn me about all other uncalled segments.

Steve,

Maybe you could try forcing the functions into the overlay map by putting in dummy calls in a conditional block:

if(0)
{
a();
b();
c();
d();
}

If the compiler optimises it all out, do:

unsigned char volatile x=0;

if(x)
etc
