Hi Volodya,

This case actually arises mainly for libraries for me (but
libraries are 
mainly what I write).  I sometimes have one library that
spans a couple 
directories, which correspond to namespaces. I suppose that
I just don't
get quite as fine-grained in these as you do.

I admit though that this may be the result of being used to
lesser
build systems like MSVS that this fine grained nature causes
much more
pain to maintain.  Perhaps with more experience using bbv2
I'd move to
a finer grained approach, but currently the library layout I
have choosen
seems most natural to me.

That being said, currently at least, I (and some others,
obviously) still
view this as a valuable feature.  

Thanks for looking into this,

-Ryan

Ehm... another bad corner case is this:

   exe a : ../../a.cpp ../../foo/b.cpp ;

It's not apparent what target directories should be used in
this case in order 
for things to work sanely. I guess we need to outlaw this
use-case.
