>Description:

gcc no longer compiles the following file.
It stopped working some time between Nov 11 and Nov 22, 2000
and still fails when using gcc built from the latest sources.

[ FYI, this showed up when trying to build tar-1.13.19
  ftp://alpha.gnu.org/gnu/tar/tar-1.13.19.tar.gz ]

  $ cat k.c
  # include <stdbool.h>
  struct foo { int x; bool bar; };
  typedef struct foo Foo;
  static const Foo f = { 0, false };

  $ cat k.i
  # 1 "/tmp/k.c"
  # 1 "/p/p/gcc-2000-11-22.09h28/lib/gcc-lib/i686-pc-linux-gnu/2.97/include/stdbool.h" 1 3
  # 2 "/tmp/k.c" 2
  struct foo { int x; _Bool bar; };
  typedef struct foo Foo;
  static const Foo f = { 0, 0 };

>How-To-Repeat:

  $ /p/p/gcc-2000-11-11.03h49/bin/gcc -c /tmp/k.c
  $ /p/p/gcc-2000-11-22.09h28/bin/gcc -c /tmp/k.c
  /tmp/k.c:4: invalid initializer
  /tmp/k.c:4: (near initialization for `f.bar')
