* 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.

definition.
