Declaring an interrupt the 4.7.0 way results in an internal compiler error on 4.9.1:
__attribute__((__interrupt__ (NMI_VECTOR)))
static void NMI_int(void)
{
}
Only if I replace __interrupt__ with 'interrupt' compilation goes fine.
OTOH if I replace __interrupt__ with some bogus value like 'paashaas' I get the following error: main.c:164:1: warning: ‘paashaas’ attribute directive ignored [-Wattributes]
