Hi !

Yes, that fixes some issues. See below for further detail...

This was changed (by me :-)) to allow identical file names in different 
directories.
This enables things like 
home/proj/moduleA/1/foo.cpp
home/proj/moduleA/2/foo.cpp

which occur regularly here (make 1=sqlio and 2=io and 3=data and you get 
the picture...)

How do you create those files ? Boost.Build internal magic will adjust 
everything to "just work" state :-)) External tools might be tweaked.

Short answer: You can't.

I've crossposted this to the Boost.Build mailing list, which is more 
appropriate.

A self-contained test case would be helpfull, too ;-))

Yours,

Jürgen
