[svn r231] Changed: warnings are no longer treated as an error. Added some comments and cleaned up CallExp::toElem a tiny bit. Fixed: struct literals always reported inplace assignment even if they allocated a temporary. Fixed: passing stuff to a D-style vararg which did inplace assignment was generated suboptimal code.

module strings1;

void f(char[11] buffer)
{
    printf("%.*s\n", buffer.length, buffer.ptr);
}

void main()
{
    char[11] buffer;
    char[] hello = "hello world";
    {buffer[] = hello[];}
    {f(buffer);}
    {f("eleven char");}
}
