Which is where I was lost ;)

The makefile already includes w32 specifics, so I guessed someone
(Alexander I'm looking at you) was using it.

By the way are we targeting a specific make on windows ? dmake ?
nmake (the msoft one) ? gnumake under cygwin ?

Haaa. The missing bit.

Ok.

Another way to look at 'bzr selftest --clean' is that some users
may want to run selftest without having to install a make (on
developer request while tracking a bug and trying patches for
example). In that case the debug session can end by a nice:

 bzr selftest --clean

and leave the user with a clean environment.

Ok, enough hype ;)

ObJoke: What about:

clean-selftest:
        bzr selftest --clean
