That's a silly statement, the build code is exactly the same. One has a warning, one doesn't. And if you only want to wake for a serial IRQ, then put the wakeup in the serial IRQ handler. If that's still not good enough, then have the main code retest for "time to wakeup" and if it fails, just go to sleep again. -Mark

Because that wakes up the processor unconditionally at the end of the interrupt service routine.

Your solution only works if you need to wake up the processor on _every_ interrupt. That's not what I need to do. > Personally, I don't like patching the compiler just to remove > a warning. Neither do I, but I dislike even more shipping code that won't build cleanly. I always use -Wall -Werror, and I'll fix the compiler before I'll ship code that won't compile without warnings. > Especially when there is a good way to avoid that warning.
