I think they'd read & match just fine without them (perhaps pwr->power would be better but it's up to you) and ac/dc can then be capitalized.

Let me give it a try. (I tried to retain the same struct fields across Linux and Windows so that its easy to maintain) Will address your remarks on other patches in the series in the new revision.
