I want to use arrays of variable length.

I want to do something like:
#ifdef __GNUC__
typedef struct {
	int size;
	char mess[0];
} SMALL_MESSAGE;
#endif

#define MAX_MESSAGE 128
typedef struct {
	int size;
	char mess[MAX_MESSAGE]
} BIG_MESSAGE;

The problem is prototypes...how do I define a prototype which reads either message...

i.e.

read_message(SMALL_MESSAGE *) and
read_message(BIG_MESSAGE *)

If I'm going to not use memory allocation routines, I want to just do:
	func()
	{
		BIG_MESSAGE mess;

		mess.size = MAX_MESSAGE;

If I'm using memory allocation routines, I can be cleverer.

How to I get around this problem?
