Update.
2003-06-15 Ulrich Drepper <drepper@redhat.com> Fix cancellation point handling wrt exception based cleanup. * io/Makefile: Compile fcntl.c, poll.c, and lockf.c with exceptions. * misc/Makefile: Compile pselect.c, readv.c, writev.c, and usleep.c with exceptions. * posix/Makefile: Compile pread.c, pread64.c, pwrite.c, pwrite64.c, sleep.c, wait.c, waitid.c, and waitpid.c with exceptions. * rt/Makefile: Compile aio_suspend.c and clock_nanosleep.c with exceptions. * signal/Makefile: Compile sigpause.c, sigsuspend.c, sigtimedwait.c, sigwait.c, and sigwaitinfo.c with exceptions. * stdlib/Makefile: Compile system.c with exceptions. * sysvipc/Makefile: Compile msgrcv.c and msgsnd.c with exceptions. * termios/Makefile: Compile tcdrain.c with exceptions. * sysdeps/generic/lockf.c: Add comment explaining the cancellation situation. * sysdeps/generic/pselect.c: Likewise. * sysdeps/posix/sigpause.c: Likewise. * sysdeps/posix/system.c: Likewise. * sysdeps/posix/waitid.c: Likewise. * sysdeps/unix/sysv/linux/sleep.c: Likewise. * sysdeps/unix/sysv/linux/usleep.c: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Major rewrite of INTERNAL_SYSCALL to not use push inside asm statement so that unwind info is correct around the syscall. * sysdeps/unix/clock_nanosleep.c: Add cancellation support. * sysdeps/unix/sysv/linux/clock_nanosleep.c: Likewise.
