Update.
2004-11-18 Ulrich Drepper <drepper@redhat.com> * libio/libio.h (_IO_FLAGS2_FORTIFY): Renamed from _IO_FLAGS2_CHECK_PERCENT_N. * debug/fprintff_chk.c: Adjust all users. * debug/printf_chk.c: Likewise. * debug/vfprintf_chk.c: Likewise. * debug/vprintf_chk.c: Likewise. * debug/vsnprintf_chk.c: Likewise. * debug/vsprintf_chk.c: Likewise. * stdio-common/vfprintf.c: Likewise. Detect missing %N$ formats. * debug/tst-chk1.c: Test detection of missing %N$ formats.
