Subject: [PATCH] fix build with glibc 2.34
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The closefrom() function which is introduced in glibc 2.34 conflicts
with the one provided by postfix.
Fixes:
| In file included from attr_clnt.c:88:
| /usr/include/unistd.h:363:13: error: conflicting types for ‘closefrom’; have ‘void(int)’
| 363 | extern void closefrom (int __lowfd) __THROW;
| | ^~~~~~~~~
| In file included from attr_clnt.c:87:
| ./sys_defs.h:1506:12: note: previous declaration of ‘closefrom’ with type ‘int(int)’
| 1506 | extern int closefrom(int);
| | ^~~~~~~~~
Upstream-Status: Backport
