X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=2a00634880adb20071686906ebb183326f2060e0;p=emacs.git

Port pdumper.c maybe_unused to C2x

Port pdumper.c to C2x, and pacify gcc 11.2.1 -Wattributes -Wunused.
* src/pdumper.c (dump_tailq_prepend):
Omit ATTRIBUTE_UNUSED, since it’s always used.
(dump_tailq_append): Remove; unused.
