Date: Thu, 22 Apr 2021 09:42:11 +0100

Hi,

The recent changes on seccomp introduced by Philipp Stephani (around commit
be8328acf9aa464f848e682e63e417a18529af9e) break the compilation when Emacs is
built within a Docker container.

The error is:

seccomp-filter.c:168:11: error: static_assert expression is not an integral constant expression
  verify ((uintptr_t) NULL == 0);
  ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
../lib/verify.h:273:32: note: expanded from macro 'verify'
