I can't find anything about *waithanjan. It looks like a very strange word, too. I am finding weidon in Old High German, veiða in Old Norse and wǣþan in Old English. The meanings of the French verbs don't make much sense either... why would a verb meaning "graze" be borrowed as "win"? The double -a- seems suspicious too... But the form gaaignier reminds me of a very different verb that exists in Gothic, gaaiginōn, which actually means "to acquire, to take possession of". That matches the meaning much better. So I don't think the current etymology of gagner and varieties is really correct at all.
Yeah, it is a strange one. If you look at the Spanish Lua error in Module:parameters at line 100: The parameter "land" is not used by this template., the root makes more sense. And then there is Lua error in Module:parameters at line 100: The parameter "land" is not used by this template., which also exhibits the odd ending. Could it be a merging of the two words?
Looks like weidanōn is from the Webster's Seventh New Collegiate Dictionary. http://www.utexas.edu/cola/centers/lrc/ielex/X/P2112.html#OHG
It still begs the question why OHG has a class 2 weak verb, though. I mean, if that's what's actually attested, we should probably reconstruct it. Besides, French had no verb chass in -o- so it had to improvise on that.
I don't know. That may be true in stressed syllables, but the prefix ga- was unstressed so it may have given a different outcome.

If gaaiginōn came into Old French via Old Provençal, the hard /g/ could have survived.
But how could it have entered Old Provençal without it being Frankish in origin? Old French is kind of... in the way between them. Of course it's possible that the word came from Alemannic instead. But is it not possible for the g- to have survived? After all if garir has g-, why can't this word?
Ok, I see. But still... if w > g survived, then g itself could have survived too. Are there any examples Germanic words with g being borrowed into French with j?
I'm guessing this is related to the oddities in the second paragraph of gain#Etymology 3? If French gagner > older gaaignier > Gothic gaaiginōn (gaaiginōn), then any /w/ > /g/ mutation seems irrelevant. And what of Spanish ganar?
