$(setup:J=" ") is basically what " ".join(setup) is in Python - it joins all elements of a list with a separator.

If that ends up empty, it means we failed to find setup script MSVC 7.1 at all. It might explain not finding includes.

Could you find the line a bit above that reads:
        
        setup = [ locate-default-setup $(command) : $(parent) : $(default-setup) ] ;

and add

        ECHO "locate-default-setup $(command:E=) : $(parent:E=) : $(default-setup:E=) -> $(setup:E=) " ;

after it and see what that outputs?

We might want to move this to boost-build_at_[hidden] though, as it's becoming rather detailed discussion.
