В си+плюсе функции могут быть перегружены: если аргумент константный,
то и значение константное; а второй прототип соответственно без const
то и другое. Когда людишки функцию вызывают, то си+плюс смотрит, какой
прототип надо выбрать.
Это написано в книжке "Страус" на странице 666.
Соответственно в string.h у функций типа strchr два прототипа:
char *strchr(char *s, int c);
const char *strchr(const char *s, int c);
