Q: Interrupts disabled during call to prevent re-entrancy

I have code that uses interrupt routines. And I got the topic header:

Quote:

>>> Warning 216 "690_v2.c" Line 67(0,1): Interrupts disabled during call to prevent re-entrancy: (RF_status)

But if I look at the function in question:

Code:

int16 RF_status()
{
int16 result;
disable_interrupts(GLOBAL);
.....

I allready disable interrupts. Why would compiler then do it again? Confused
