I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

remote: *** 913:

Running the test on a 4.4 kernel within KVM, the precision used on
ITIMER_VIRTUAL and ITIMER_PROF seems to different than the one used
for ITIMER_REAL (it seems the same used for CLOCK_REALTIME_COARSE and
CLOCK_MONOTONIC_COARSE). I did not see it on other kernels, for
instance 5.11 and 4.15.
To avoid trying to guess the resolution used, do not check the
nanosecond internal values for the specific timers.
Checked on i686-linux-gnu with a 4.4 kernel.

The recent change to use __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64 to avoid
doing 64-bit checks on some platforms broke the test for hurd where
__KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64 is not defined. With error:
tst-itimer.c: In function 'do_test':
tst-itimer.c:103:11: error: '__KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64' undeclared (first use in this function)
103 | if (__KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tst-itimer.c:103:11: note: each undeclared identifier is reported only once for each function it appears in
Define a support helper to detect when setitimer and getitimer support
64-bit time_t.
Fixes commit 6e8a0aac2f ("time: Fix overflow itimer tests on 32-bit
systems").

On the port of OpenRISC I am working on and it appears the rv32 port
we have sets __TIMESIZE == 64 && __WORDSIZE == 32. This causes the
size of time_t to be 8 bytes, but the tv_sec in the kernel is still 32-bit
causing truncation.
The truncations are unavoidable on these systems so skip the
testing/failures by guarding with __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64.
Also, futher in the tests and in other parts of code checking for time_t
overflow does not work on 32-bit systems when time_t is 64-bit. As
suggested by Adhemerval, update the in_time_t_range function to assume
32-bits by using int32_t.
This also brings in the header for stdint.h so we can update other
usages of __int32_t to int32_t as suggested by Adhemerval.
