Always define off_t, mode_t, pid_t
* io/fcntl.h: Always define mode_t, off_t, pid_t and use these types for creat, creat64, lockf, posix_fadvise, posix_fallocate. [__USE_LARGEFILE64 && !__off64_t_defined]: Define off64_t. [__USE_LARGEFILE64]: Use off64_t in declaration of lock64, posix_fadvise64, posix_fallocate64.
