Use a struct tag, rather than the typdef tag for your storage type, as:
typedef struct _TMenu
{
...
struct _TMenuItem items[];
}
TMenu;
typedef struct _TMenuItem
{
...
struct _TMenu *ptr;
...
}
MenuItem;

Subject: [avr-gcc-list] Typdef chick 'n egg situation.. way out ?
Hi list,
Problem: I have two typdef's statement, each type contains a pointer to
the other type ! Hmmm....
typedef TMenuItem struct {
char text[20];
TMenu *ptr;
void (*fptr)();
};
typedef TMenu struct {
uint8_t nb;
char title[20];
TMenuItem items[];
};
I am basically rewriting (following a computer crash..) a program I did
3+ years ago.. all from memory. Back then ISTR some kind soul on here,
sorted me out with something he called "forward declaration"... but I
can't seem to manage to find this particular post in the list archive
sadly.
I think it was a line just saying "TMenu" will be defined further down,
don't worry Mister GCC and just accept my TMenuItem struct below, you
will find TMenu soon enough. Something to that effect ! ;-)
TIA...
Regards,
