Indeed. One of its features. Apparently you have a defective string.h: The lines in question are last_key = strrchr (key_path, '/'); and strrchr is declared as char* strrchr(const char *, int); in the POSIX standard [1]. 'key_frame' is the 'const char*' argument in the function arguments. I can const_cast<char*>(key_frame) in there, but I'd rather not.
