	* misc/sys/cdefs.h (__extern_inline, __extern_always_inline): Only
	define in C++ for GCC 4.3+, in C++ always use __gnu_inline__
	attribute.
	* include/features.h (__USE_EXTERN_INLINES): Define only when
	__extern_inline is defined.
	* stdlib/stdlib.h: Include bits/stdlib.h when __extern_always_inline
	is defined instead of when not __cplusplus.
	* misc/sys/syslog.h: Include bits/syslog.h when __extern_always_inline
	is defined instead of when not __cplusplus.
	* socket/sys/socket.h: Include bits/socket2.h when
	__extern_always_inline is defined instead of when not __cplusplus.
	* libio/stdio.h: Include bits/stdio2.h when __extern_always_inline
	is defined instead of when not __cplusplus.
	* posix/unistd.h: Include bits/unistd.h when __extern_always_inline
	is defined instead of when not __cplusplus.
	* string/string.h: Include bits/string3.h when __extern_always_inline
	is defined instead of when not __cplusplus.
	* wcsmbs/wchar.h: Include bits/wchar2.h when __extern_always_inline
	is defined instead of when not __cplusplus.
	(btowc, wctob): Don't guard the inlines with ifndef __cplusplus.
	* io/fcntl.h: Don't include bits/fcntl2.h if __extern_always_inline
	is not defined.
	* misc/bits/syslog-ldbl.h: Guard *_chk stuff with
	defined __extern_always_inline instead of !defined __cplusplus.
	* libio/bits/stdio-ldbl.h: Likewise.
	* wcsmbs/bits/wchar-ldbl.h: Likewise.
	* misc/bits/syslog.h (syslog): Don't define for C++.
	(vsyslog): Use __extern_always_inline function for C++ instead of
	a macro.
	* libio/bits/stdio.h (__STDIO_INLINE): Define to __extern_inline
	whenever that macro is defined.
	(vprintf): Don't provide the inline for C++.
	(fread_unlocked, fwrite_unlocked): Don't define the macros for C++.
	* libio/bits/stdio2.h (sprintf, snprintf, printf, fprintf): Don't
	define the macros for C++.

	stat64, lstat64, fstat64, fstatat64): Don't define if not
	__USE_EXTERN_INLINES.

	(memcpy, memmove, mempcpy, memset, bcopy, bzero, strcpy, stpcpy,
	strncpy, strcat, strncat): Define as __extern_always_inline
	functions instead of macros for C++.
	* math/bits/cmathcalls.h: Guard __extern_inline routines with
	defined __extern_inline.
	* sysdeps/alpha/fpu/bits/mathinline.h (__MATH_INLINE): Define
	to __extern_inline whenever that macro is defined.

	prototypes.  Only provide __extern_inline routines if
	__USE_EXTERN_INLINES.
	* debug/Makefile: Add rules to build and run tst-{,lfs}chk{4,5,6}
	tests.
	* debug/tst-chk1.c (do_prepare, do_test): Allow compilation as C++.
	For now avoid some *printf tests in C++.  Skip all testing
	if __USE_FORTIFY_LEVEL is defined, but __extern_always_inline macro
	is not.
