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

/* This template provides testing for the *cvt family of functions,
|
|
which deal with double or long double types. In order to use the
|
|
template, the following macros must be defined before inclusion of
|
|
this template:
|
|
|
|
FLOAT: The floating-point type, i.e. double or long double.
|
|
|
|
ECVT: Appropriate *ecvt function for FLOAT, i.e. ecvt or qecvt.
|
|
FCVT: Likewise for *fcvt, i.e. fcvt or qfcvt.
|
|
ECVT_R: Likewise for *ecvt_r, i.e. ecvt_r or qecvt_r.
|
|
FCVT_R: Likewise for *fcvt_r, i.e. fcvt_r or qfcvt_r.
|
|
|
|
PRINTF_CONVERSION: The appropriate printf conversion specifier with
|
|
length modifier for FLOAT, i.e. "%f" or "%Lf".
|
|
|
|
EXTRA_ECVT_TESTS: Additional tests for the ecvt or qecvt function
|
|
that are only relevant to a particular floating-point type and
|
|
cannot be represented generically. */
