(__glob64): Define GLIBC_2_27 versioned symbol instead of glob64. * sysdeps/gnu/glob-lstat-compat.c: New file. * sysdeps/gnu/glob64-lstat-compat.c: New file. --- sysdeps/gnu/glob-lstat-compat.c | 38 +++++++++++++++++++++++++++++++ sysdeps/gnu/glob64-lstat-compat.c | 48 +++++++++++++++++++++++++++++++++++++++ sysdeps/gnu/glob64.c | 7 +++--- 3 files changed, 90 insertions(+), 3 deletions(-) create mode 100644 sysdeps/gnu/glob-lstat-compat.c create mode 100644 sysdeps/gnu/glob64-lstat-compat.c (limited to 'sysdeps') diff --git a/sysdeps/gnu/glob-lstat-compat.c b/sysdeps/gnu/glob-lstat-compat.c new file mode 100644 index 0000000000..7cb52d4fee --- /dev/null +++ b/sysdeps/gnu/glob-lstat-compat.c @@ -0,0 +1,38 @@ +/* Compat glob which does not use gl_lstat for GLOB_ALTDIRFUNC. + GNU version + Copyright (C) 2017-2018 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
