I don't think this set of complications is worth the risk
destabilizing those stable branches.

Just to be clear, for 2) I was thinking to pick up the minimal parts
you have changed in win32env.c and add src/port/setenv.c to add the
fallback implementation of setenv(), without changing anything else.
This also requires grabbing the small changes within pgwin32_putenv(),
visibly.
