Subject: Nickolai Zeldovich writes: Currently, tcgetpgrp() in uClibc uses an
int to store a PID (fetched via ioctl TIOCGPGRP). This causes problems on
platforms where pid_t is defined to be larger (e.g., uint64_t). Other
functions in termios, such as tcgetsid() and tcsetpgrp(), already pass a
pid_t to ioctl(), so the following patch does the same in tcgetpgrp() as
well.
