Wine eventually compiled but now it can't run Steam. Clean profile, clean install in the new profile et all... Log file attached.
If current Wine compiled by yourself does run Steam, it means that some patch in between fixed it. I don't recall any such patch at the moment though...
One thing you could do is to first make a "reverse bisect" to find which patch did that (i.e. if Steam starts do "git bisect bad", if it fails "git bisect good"), then restart the original bisect but additionally cherry-picking this fix where needed...
