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

/* We need a special version of the `mcount' function since for ix86 it
|
|
must not clobber any register. This has several reasons:
|
|
- there is a bug in gcc as of version 2.7.2.2 which prohibits the
|
|
use of profiling together with nested functions
|
|
- the ELF `fixup' function uses GCC's regparm feature
|
|
- some (future) systems might want to pass parameters in registers. */
