Not a real bug, just an "improvement-request". I understand that SIGNAL and
INTERRUPT are now depracated. But the new header-files break old code
(compile-time-error) in a way that could be avoided: There is old code (at
least I've done some code like this) where just SIGNAL is used in
"device-driver"-modules. There has been no need for sei or cli in this
source-files so only <avr/signal.h> gets included (no interrupt.h) which
worked with older releases of avr-libc. Now signal.h does "nothing" but print
a #warning. This breaks the compatibility and could be avoided if signal.h
would also include interrupt.h.
