If GetLastError returned a 64-bit value on 64-bit Windows, as Paul thought, then your cast wouldn't be correct, of course, because 'unsigned long' is a 32-bit type on all versions of Windows.
I was responding only to the suggestion in its immediate context, not any actual statement (or other confusion) about GetLastError. Paul's text mentions "unsigned int" and "unsigned long". If those are the only two choices, the cast to unsigned long will always succeed.
