You'd still need to move the code - since currentl objdir handling is
done before the command line is parsed.

I use -current make on all my boxes - 1.4.x onwards. I've not noticed
any issues.

You can just as easily clear .MAKEOVERRIDES.

Besides, command line options suck for something you want every time.
You end up forcing people to write aliases/scripts to wrap make
to provide all the options - at which point you may as well have a
script that sets up the environment before running make.

Anyway, this sounds an interesting idea.
