* misc/sys/cdefs.h (__va_arg_pack): Define for GCC 4.3+.
* misc/bits/syslog.h (syslog): When __va_arg_pack is defined, implement as __extern_always_inline function. (vsyslog): Define as __extern_always_inline function unconditionally. * libio/bits/stdio2.h (sprintf, snprintf, printf, fprintf): When __va_arg_pack is defined, implement as __extern_always_inline functions. (vsprintf, vsnprintf, vprintf, vfprintf): Define as __extern_always_inline functions unconditionally. * libio/bits/stdio.h (vprintf): Ifdef out the inline when bits/stdio2.h will be included. * wcsmbs/bits/wchar2.h (__swprintf_alias): New redirect. (swprintf, wprintf, fwprintf): When __va_arg_pack is defined, implement as __extern_always_inline functions. (vswprintf, vwprintf, vfwprintf): Define as __extern_always_inline functions unconditionally. * debug/tst-chk1.c (do_test): Enable remaining tests for C++. 2007-09-03 Jakub Jelinek <jakub@redhat.com> * 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++. (vsprintf, vsnprintf, vprintf, vfprintf): Define as __extern_always_inline functions for C++. * io/sys/stat.h (stat, lstat, fstat, fstatat, mknod, mknodat, stat64, lstat64, fstat64, fstatat64): Don't define if not __USE_EXTERN_INLINES. * wcsmbs/bits/wchar2.h: Fix #error message.

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. * debug/tst-chk4.cc: New file. * debug/tst-chk5.cc: New file. * debug/tst-chk6.cc: New file. * debug/tst-lfschk4.cc: New file. * debug/tst-lfschk5.cc: New file. * debug/tst-lfschk6.cc: New file. * include/wchar.h (__vfwprintf_chk, __vswprintf_chk): Avoid prototypes in C++. * include/stdio.h (__sprintf_chk, __snprintf_chk, __vsprintf_chk, __vsnprintf_chk, __printf_chk, __fprintf_chk, __vprintf_chk, __vfprintf_chk, __fgets_unlocked_chk, __fgets_chk): Likewise.
