-Subject: [PATCH] Reinstate various pieces backed out from smart_rename changes
-
-In the interests of a stable release various last minute smart_rename
-patches were backed out of the 2.36 branch. The main reason to
-reinstate some of those backed out changes here is to make necessary
-followup fixes to commit 8e03235147a9 simple cherry-picks from
-mainline. A secondary reason is that ar -M support isn't fixed for
-pr26945 without this patch.
-
- PR 26945
- * ar.c: Don't include libbfd.h.
- (write_archive): Replace xmalloc+strcpy with xstrdup.
- * arsup.c (temp_name, real_ofd): New static variables.
- (ar_open): Use make_tempname and bfd_fdopenw.
- (ar_save): Adjust to suit ar_open changes.
- * objcopy.c: Don't include libbfd.h.
- * rename.c: Rename and reorder variables.
-
