This is because mod-test.c shouldn’t use source code from lib,
but it does need to include <config.h>.
* lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c:
* lib-src/make-docfile.c, lib-src/movemail.c:
* lib-src/seccomp-filter.c, src/dynlib.h, src/lisp.h:
* src/syssignal.h, src/sysstdio.h, src/systhread.h, src/tparam.h:
Include <attribute.h>.
* src/conf_post.h: Do not include <attribute.h>.
All uses of attribute.h macros replaced with their _GL_ equivalents.

* lib-src/etags.c (regexp): Omit member force_explicit_name,
since it’s always true.  All uses removed.  This lets us
remove calls to strlen (name) where GCC isn’t smart enough
to deduce that name must be nonnull.
* lib-src/movemail.c (main): Fix bug that could cause
link (tempname, NULL) to be called.
* src/emacs.c (argmatch): Break check into two ‘if’s,
since GCC doesn’t seem to be smart enough to check the single ‘if’.
* src/gtkutil.c (xg_update_menu_item): Fix bug where strcmp
could be given a NULL arg.
* src/xfont.c (xfont_list_family): Use nonnull value for dummy
initial value.

Run "TZ=UTC0 admin/update-copyright".

* src/emacs.c (main): Mark the return from strerror as a constant,
since it shouldn't be changed (bug#43982).

* lib-src/movemail.c (pfatal_and_delete): Ditto.

Copyright-paperwork-exempt: yes

Run "TZ=UTC0 admin/update-copyright $(git ls-files)".

2fcf2df Fix copyright years by hand
26bed8b Update copyright year to 2019
2814292 Fix value of default frame height.  (Bug#33921)

Run 'TZ=UTC0 admin/update-copyright $(git ls-files)'.

* configure.ac: Do not use GCC 8’s new -Wcast-align flag.
* lib-src/ebrowse.c (xmalloc):
* lib-src/emacsclient.c (xmalloc, xstrdup):
* lib-src/etags.c (xmalloc):

* src/dispnew.c (new_glyph_pool):

* src/term.c (tty_menu_create):
* src/tparam.h (tparam):
Use ATTRIBUTE_MALLOC.  Also see GCC bug 85562.
* lib-src/emacsclient.c (fail):
Do not dereference a null pointer.
* src/frame.c (delete_frame):
Add a decl with UNINIT to work around GCC bug 85563.
* src/menu.h (finish_menu_items):
Do not use attribute const.
* src/regex.c (analyze_first): Use FALLTHROUGH, not a comment.

Run admin/update-copyright.
