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

On entry to 'getopt', zero means this is the first call; initialize.

|
|
Return the option character from OPTS just read. Return -1 when
|
|
there are no more options. For unrecognized options, or options
|
|
missing arguments, 'optopt' is set to the option letter, and '?' is
|
|
returned.
|
|
|
|
The OPTS string is a list of characters which are recognized option
|
|
letters, optionally followed by colons, specifying that that letter
|
|
takes an argument, to be placed in 'optarg'.
|
|
|
|
If a letter in OPTS is followed by two colons, its argument is
|
|
optional. This behavior is specific to the GNU 'getopt'.
|
|
|
|
The argument '--' causes premature termination of argument
|
|
scanning, explicitly telling 'getopt' that there are no more
|
|
options.
|
|
|
|
If OPTS begins with '-', then non-option arguments are treated as
|
|
arguments to the option '\1'. This behavior is specific to the GNU
|
|
'getopt'. If OPTS begins with '+', or POSIXLY_CORRECT is set in
|
|
the environment, then do not permute arguments.
|
|
|
|
For standards compliance, the 'argv' argument has the type
|
|
char *const *, but this is inaccurate; if argument permutation is
|
|
enabled, the argv array (not the strings it points to) must be
|
|
writable. */
