Agreed. I'll look into fixing CPU_Interrupt_frame up as time permits.

If you get it to compile before addressing the context switch
synchronization point, one thought is to put an ifdef RTEMS_SMP with a
#error where the fix needs to go with the message referencing the ticket

At least that way, it still doesn't compile until that issue is also fixed.
As Sebastian said, that failure is more subtle than a compile error.

Appreciate the help and follow-ups, thanks!
