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 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...
remote: *** error: lines with trailing whitespace found
remote: error: hook declined to update refs/heads/master
It replaces the internal usage of __{f,l}xstat{at}{64} with the
__{f,l}stat{at}{64}. It should not change the generate code since
sys/stat.h explicit defines redirections to internal calls back to
xstat* symbols.
Checked with a build for all affected ABIs. I also check on
x86_64-linux-gnu and i686-linux-gnu.

The recent fexecve changes broke the build on (at least) alpha (maybe
other configurations, that was the first breakage I saw in my
build-many-glibcs.py run):

This patch fixes this similarly to previous fixes for such issues: use
&argv[0] and &envp[0] as the syscall macro arguments. Tested
(compilation only) for alpha-linux-gnu with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/fexecve.c (fexecve) [__NR_execveat]:
Explicitly take address of first element of array arguments in
call to INLINE_SYSCALL.
* include/wctype.h: Define iswalnum with libc_hidden_proto.
* include/signal.h: Define raise with libc_hidden_proto.
* sysdeps/unix/sysv/linux/fexecve.c (fexecve): Use __snprintf and
__execve instead of snprintf and execve.
