There is an extension to the c-language that is supposed to be supported by all gcc targets. The idea is to support functions inside functions so that e.g. something like

int foo3 ( int func(int), int a)
{ return a + a * func (27);

foo (int a, int b)
    foo2 (int c)
    { return c + b;

    return foo3 (&foo2, a);

is considered to be legal code for gcc. The avr port does presently lack support for this extension.
Bleah. :-P
I wouldn't even know why that would even be used.

It would make it easy to convert large pascal code.
