There's not really any way to avoid that type of thing. More often than
not, in C, you *meant* to do that kind of thing. You might declare a
structure something like this:

typedef
struct
{
    int count
    long list[ 1 ];
} x;

Where your intent is to use count as the number of items in the list, rather
than somehow limiting the list to one element, as it's declared. C assumes
that you know what you're doing and mean to do what you say.

If you want some kind of checked access array, you can build one using C++,
by overloading the [] operator and checking some kind of length field before
allowing the operation...
