I don't know about the easiest, but this worked for me and if DJGPP doesn't give
an error, it works.

void **make_2d_array(size_t element_size, size_t left, size_t right)
{    // array[left][right] for clarity
    void **ret;
    int i;

    // how do you 'new' a number like malloc()?
    ret = malloc(4 * left); // array of far pointers
    if (!ret)
        return NULL;

    for (i = 0; i < right; i++)
        ret[i] = malloc(element_size * right);

    for (i = 0; i < right; i++)
        if (!ret[i])
            return NULL;
    return ret;
}

This worked for me, though it seems to be a large waste.
