>Description:
The following error message is produced when I compile
the source code (gcc -S foo.c):
foo.c:14: initializer element is not constant
foo.c:14: (near initialization for `registers_pid_1')
foo.c:14: initializer element is not constant

I think that this behaviour contradicts to C99, 6.7.8-13. And note that gcc-2.95.3 compiles this code successfully. 
>How-To-Repeat:
typedef struct t_inf_id {
  int board;
  int processor;
  int process;
  int thread;
} t_inf_id;

typedef struct inf_id {
  unsigned long machine;
  t_inf_id tid;
  int att_flag;
} inf_id;

inf_id registers_pid_1 = ((inf_id) {0, (t_inf_id) {0, 0, -1, -1}, 0}); /* Error!*/
inf_id registers_pid_2 = ((inf_id) {0, {0, 0, -1, -1}, 0}); /* OK! */
t_inf_id t_registers_pid = ((t_inf_id) {0, 0, -1, -1});     /* OK! */
