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: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

/* The fallback definitions, for when __WCHAR_MAX__ or __WCHAR_MIN__
|
|
are not defined, give the right value and type as long as both int
|
|
and wchar_t are 32-bit types. Adding L'\0' to a constant value
|
|
ensures that the type is correct; it is necessary to use (L'\0' +
|
|
0) rather than just L'\0' so that the type in C++ is the promoted
|
|
version of wchar_t rather than the distinct wchar_t type itself.
|
|
Because wchar_t in preprocessor #if expressions is treated as
|
|
intmax_t or uintmax_t, the expression (L'\0' - 1) would have the
|
|
wrong value for WCHAR_MAX in such expressions and so cannot be used
|
|
to define __WCHAR_MAX in the unsigned case. */
