The minimum acceptable standard would be for

    b2 address-model=32,64 stage

to work under Windows. Whether this is done via separate directories or 
separate names is up to us; so far people seem to prefer separate 
directories, but either way is good enough. Typically, separate directories 
are more convenient because one only needs to change the library path to 
switch between 32/64; separate names however are more convenient when 
autolinking, in which case nothing needs to change, and we already encode 
build settings into the name on Windows.
