That's because it's not error from Boost.Build point of view. It's perfectly 
ok to refer to all targets in other project with "/number' syntax. I'm not 
sure it's worth issuing a warning message in this case. Or, to put in other 
way, I'm not sure when such warning messages can be issued. 

One use case for '/number' syntax is 

stage all : /number ;

to stage everything in /number. The warning in this case is not necessary, and 
I don't know how BB can distinguish those cases.
