Subject: [PATCH] glob: Do not assume glibc glob internals.
|
|
It has been proposed that glibc glob start using gl_lstat,
|
which the API allows it to do. GNU 'make' should not get in
|
the way of this. See:
|
https://sourceware.org/ml/libc-alpha/2017-09/msg00409.html
|
|
* dir.c (local_lstat): New function, like local_stat.
|
(dir_setup_glob): Use it to initialize gl_lstat too, as the API
|
requires.
