>Description:
GNU gnu99 is missing a feature, compound literals for static initializers should be accepted in gnu99 mode, as they are in gnu89 mode.

http://gcc.gnu.org/onlinedocs/gcc/Compound-Literals.html#Compound%20Literals
typedef struct A { int i; } At;

void foo() {
  static At a = (At){0};
  static int y[] = (int []) {1, 2, 3};
}

bash-2.05a$ gcc -c -xc t3.m -std=gnu99
t3.m: In function `foo':
t3.m:4: initializer element is not constant
t3.m:5: array initialized from non-constant array expression
