I think I do. One of the problems here appears to be that nescc adds
__attribute__(interrupt) to _both_ function declaration and definition.
The documentation of recent gcc versions states that function attributes
are only allowed at function declaration. The other problem is that
gcc does not handle this in a more graceful manner.
You can work around this by applying the attached patch to your nescc.
