[svn r123] Fixed some typeinfo module name mismatches. Fixed D-style varargs returning through pointer. Fixed converting nested function to delegate. Added std.string and std.format to Phobos.

module bug4;

int func(int i)
{
    i += 2;
    i -= 3;
    return i;
}

void main()
{
    assert(func(4) == 3);
}
