resolv: Move libanl into libc (if libpthread is in libc) The symbols gai_cancel, gai_error, gai_suspend, getaddrinfo_a, __gai_suspend_time64 were moved using scripts/move-symbol-to-libc.py. For Hurd (which remains !PTHREAD_IN_LIBC), a few #define redirects had to be added because several pthread functions are not available under __. (Linux uses __ prefixes for most hidden aliases, and has to in some cases to avoid linknamespace issues.) 2021-07-02 09:45:00 +00:00			`/* Placeholder compatibility symbols for libanl.`
Update copyright dates with scripts/update-copyrights 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 2022-01-01 18:54:23 +00:00			`Copyright (C) 2021-2022 Free Software Foundation, Inc.`
