гораздо больше. Приведенный вами пример тоже используется, когда
переменные принадлежат определенному контексту, lwip целиком на
этом. Подразумевается, что количество глобальных переменных
небольшое, например счетчик системного таймера. Большое количество
глобальных перменных без явной на то необходимости, а также
активное использование extern говорит о низкой квалификации
программиста.
