No, only function *declarations* inside other functions are permitted,
but not function *definitions*.

Thus:

    int main(void) {
	extern void foo(void);

	void();
	return 0;
    }

is allowed, but:


    int main(void) {
	void foo(void) {
	    printf("hello\n");
	}

	void();
	return 0;
    }

is not.

>(it has a clear modular reason).

There is a good technical reason why it is not allowed. It makes
function pointers very difficult to implement and unintuitive to use. 

Nevertheless, gcc implements it as an extension.
