Thanks for checking that.
As MSDN[1] said, "Do not use GetLastError with the return values of this
(SHFileOperation) function."

I think wine's implement of SHFileOperation needs a big change.
Before hacking it, I hope there could be sufficient testcases to
help me understand that function.

I had to admit that I'm lack of experience, and I don't know
how to judge if a testcase is necessary.

Thank you very much.
