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

/* Before including this file, the including file must have included
|
|
<bits/environments.h> (generally via <unistd.h>) and must have
|
|
defined the following macros, exactly one of which will be called
|
|
for each POSIX environment:
|
|
|
|
KNOWN_PRESENT_ENVIRONMENT, for POSIX environments that are known to
|
|
be supported in this libc.
|
|
|
|
KNOWN_ABSENT_ENVIRONMENT, for POSIX environments that are known not
|
|
to be supported on this system.
|
|
|
|
UNKNOWN_ENVIRONMENT, for POSIX environments not supported in this
|
|
libc but possibly supported by another libc on the same system,
|
|
that can be selected using the same compiler but different
|
|
compilation options.
|
|
|
|
Each macro has arguments (SC_PREFIX, ENV_PREFIX, SUFFIX). The
|
|
corresponding argument to sysconf is _SC_##SC_PREFIX##_##SUFFIX.
|
|
The environment name, as used with getconf, is
|
|
ENV_PREFIX##_##SUFFIX, and the corresponding macro is the same with
|
|
a leading "_".
|
|
|
|
In addition, the macros START_ENV_GROUP and END_ENV_GROUP must be
|
|
defined. These are called with arguments V5, V6, V7 before and
|
|
after the relevant groups of environments. */
