#define max(x,y) ((x)>(y)?(x):(y))

struct Bintree{
        int element;
        struct Bintree *left;
        struct Bintree *right;
};

typedef struct Bintree* Tree;

int height(Tree T)
{
        if(T->right==T->right->left)
                return -1;
        else
                return (1 + max(height(T->left), height(T->right)))
}

Instead of checking the condition for node==NULL check if node->right->left.
This has got nothing to do with BST by the way..
