Can you actually do that, legally?  I thought the copyright assignments only applied to the DLL, not to setup.exe, so all setup.exe contributors retained their copyright.

That’s what I was told by cgf back when I did my assignment prior to contributing some work to the tar handling, way back when Robert Collins was the lead on the project.  cgf said I didn’t need to go to that trouble after I’d already sent it in.

I can’t say I’m wild about GPLv3, for reasons which don’t have to be rehashed here, being well-documented already:

What actual problem are you trying to solve with the change?
