Current master fails to compile

  In file included from lisp.h:35:0,
                   from alloc.c:33:
  alloc.c: In function 'allocate_pseudovector':
  alloc.c:3414:31: error: expression in static assertion is not constant
     verify (size_max + rest_max <= VECTOR_ELTS_MAX);

  Makefile:384: recipe for target `alloc.o' failed
  make[1]: *** [alloc.o] Error 1

I see this both on GNU/Linux and on MS-Windows.
