./configure --enable-check-lisp-object-type

[Lars Ingebrigtsen <larsi@gnus.org>]

For the first time in a while I enabled the Lisp object type, and I was
given a wall of

dispnew.c:6593:1: note: in expansion of macro ‘DEFUN’
 6593 | DEFUN ("internal-show-cursor-p", Finternal_show_cursor_p,
      | ^~~~~
lisp.h:3179:5: warning: missing braces around initializer [-Wmissing-braces]
 3179 |     {{{{ PVEC_SUBR << PSEUDOVECTOR_AREA_BITS },                         \
      |     ^

for every DEFUN.  That's new, isn't it?  (This is on Debian/bookworm.)

This is from this:

#define DEFUN(lname, fnname, sname, minargs, maxargs, intspec, doc)	\
  SUBR_SECTION_ATTRIBUTE                                                \
  static union Aligned_Lisp_Subr sname =                                \
     {{{ PVEC_SUBR << PSEUDOVECTOR_AREA_BITS },				\
       { .a ## maxargs = fnname },					\
       minargs, maxargs, lname, {intspec}, 0}};				\
   Lisp_Object fnname

That seems like beaucoup de braces, so is that a gcc bug or something?

(Adding more braces makes compilation fail.)
