The problem is a result of these dependencies:

INCLUDES x.cpp : x.bar ;
DEPENDS <object(c-scanner)>x.cpp : x.cpp ;

The result is that <object(c-scanner)>x.cpp
(which binds to x.cpp) depends on x.bar.
I think this can be solved by changing DEPENDS
to INCLUDES, but this causes other problems.
The main problem of course, is that Boost.Build
doesn't have a way to specify a dependency on a
target that refers to the same file.  The
correct behavior is a cross between DEPENDS
and INCLUDES.  The result that we want is:

<object(c-scanner)>x.cpp -> x.cpp
<object(c-scanner)>x.cpp (internal node) -> x.cpp (internal node)

INCLUDES gives

<object(c-scanner)>x.cpp (internal node) -> x.cpp
<object(c-scanner)>x.cpp (internal node) -> x.cpp (internal node)

and DEPENDS gives

<object(c-scanner)>x.cpp -> x.cpp
<object(c-scanner)>x.cpp -> x.cpp (internal node)
