commit c5c792092b57687ae3ebecbe8645fa71ddb19f8c
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Thu Feb 2 07:49:02 2023 -0500
cdefs: Limit definition of fortification macros
Define the __glibc_fortify and other macros only when __FORTIFY_LEVEL >
0. This has the effect of not defining these macros on older C90
compilers that do not have support for variable length argument lists.
Also trim off the trailing backslashes from the definition of
__glibc_fortify and __glibc_fortify_n macros.

Author: Andreas Schwab <schwab@suse.de>
Date: Thu Jan 26 14:25:05 2023 +0100
Use 64-bit time_t interfaces in strftime and strptime (bug 30053)
Both functions use time_t only internally, so the ABI is not affected.

commit 11ad405fd4c4c9f320d461d9ae1dd2e087cc8c32
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Wed Dec 29 10:20:46 2021 -0300
elf: Fix 64 time_t support for installed statically binaries
The usage of internal static symbol for statically linked binaries
does not work correctly for objects built with -D_TIME_BITS=64,
since the internal definition does not provide the expected aliases.
This patch makes it to use the default stat functions instead (which
uses the default 64 time_t alias and types).
Checked on i686-linux-gnu.
