Reduced testcase.

As Eli Friedman requested in
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2009-February/004474.html reporting
it here.

Here is a code causing problem:

struct __gconv_step_data {};

typedef struct __gconv_info
  void * dumb;
  __extension__ struct __gconv_step_data __data [];
} *__gconv_t;

typedef union
  struct __gconv_info __cd;
    struct __gconv_info __cd;
    struct __gconv_step_data __data;
  } __combined;
} _G_iconv_t;

reduced.c:15:25: error: variable sized type '__cd' must be at end of struct or
    struct __gconv_info __cd;

union _G_iconv_t definition is in <_G_config.h>, struct _gconv_info in
