Fixed on trunk with r231665.

$ cat x.c && /home/msebor/build/gcc-trunk-svn/gcc/xgcc

typedef struct {
 unsigned char dir;
 int data[];
} AiDefaultRailBlock;
static const AiDefaultRailBlock _raildata_ai_0 = { 1,  { 0,  4 }  };
x.c:5:67: warning: initialization of a flexible array member [-Wpedantic]
