the .WAIT is to separate the "depend" from the "all".. since each of them
is recursive in themselves, it should expand to

        depend(.)
        depend(subdir)
        .WAIT
        all(.)
        all(subdir)

but I could be wrong - I don't know if the .WAIT is strictly needed

well indeed, and mrg did suggest that the xorg-server code could or should
be moved around so that "compile" and "subdir" don't happen in the same
directory but perhaps its not the only instance of this
