>Description:

GCC fails to assign the composite type properly for multiple extern
declarations of an array in nested blocks.

>How-To-Repeat:

See gcc.c-torture/compile/20001018-1.c (XFAIL).  This was inspired by
a discussion on comp.std.c.

void
foo (void)
{
  extern char i[10];

  {
    extern char i[];
    char x[sizeof (i) == 10 ? 1 : -1];
  }
}
