Update.
* include/atomic.h: Define atomic_increment_val, atomic_decrement_val, and atomic_dealy is not already defined. * sysdeps/i386/i486/bits/atomic.h: Define atomic_delay. * sysdeps/x86_64/bits/atomic.h: Likewise. * miscd/sys/cdefs.h (__NTH): New macro. (__THROW): Define using nothrow attribute for C code and gcc >= 3.2. (__REDIRECT_NTH): New macro. * argp/argp.h: Use __NTH and __REDIRECT_NTH where necessary. * ctype/ctype.h: Likewise. * dirent/dirent.h: Likewise. * io/fcntl.h: Likewise. * io/sys/sendfile.h: Likewise. * io/sys/stat.h: Likewise. * io/sys/statfs.h: Likewise. * io/sys/statvfs.h: Likewise. * libio/bits/stdio.h: Likewise. * misc/sys/mman.h: Likewise. * posix/unistd.h: Likewise. * resource/sys/resource.h: Likewise. * rt/aio.h: Likewise. * signal/signal.h: Likewise. * stdlib/stdlib.h: Likewise. * string/argz.h: Likewise. * string/string.h: Likewise. * sysdeps/generic/inttypes.h: Likewise. * sysdeps/i386/fpu/bits/mathinline.h: Likewise. * sysdeps/powerpc/fpu/bits/mathinline.h: Likewise. * sysdeps/s390/fpu/bits/mathinline.h: Likewise. * sysdeps/x86_64/fpu/bits/mathinline.h: Likewise. * sysdeps/unix/sysv/linux/bits/socket.h: Likewise. * sysdeps/unix/sysv/linux/bits/sys/sysmacros.h: Likewise. * wcsmbs/wchar.h: Likewise. * sysdeps/generic/glob.c: Use __PMT isntead of __P where appropriate. * resolv/gethnamaddr.c (getanswer): Remove __P use in variable definition. * io/sys/poll.h: Remove __THROW from poll prototype, it's a cancellation point.
