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

/* Authors of new ports of the GNU C Library must override this file
|
|
with their own bits/errno.h in an appropriate subdirectory of
|
|
sysdeps/. Its function is to define all of the error constants
|
|
from C2011 and POSIX.1-2008, with values appropriate to the
|
|
operating system, and any additional OS-specific error constants.
|
|
|
|
C2011 requires all error constants to be object-like macros that
|
|
expand to "integer constant expressions with type int, positive
|
|
values, and suitable for use in #if directives". Moreover, all of
|
|
their names must begin with a capital E, followed immediately by
|
|
either another capital letter, or a digit. It is OK to define
|
|
macros that are not error constants, but only in the implementation
|
|
namespace.
|
|
|
|
errno.h is sometimes included from assembly language. Therefore,
|
|
when __ASSEMBLER__ is defined, bits/errno.h may only define macros;
|
|
it may not make any other kind of C declaration or definition.
|
|
Also, the error constants should, if at all possible, expand to
|
|
simple decimal or hexadecimal numbers. */
