Well, I'm from Germany, where the name kind of comes from. For me it's more than old fashioned. The men I know who are called
Wolfgang are all 40+ if not 50+. "
Wolf" has the same meaning in Germany as in English speaking countries and we also know the word "gang", even though it's got a different meaning (you could translate it as "corridor" - I think BTN is wrong here with "path"), still nobody laughes at those who are called
Wolfgang.
