Subject: [Boost-build] what exactly does determine-target-name ?

I encounter an issue with a custom generator. It used to work with an
older boost build (2.0-m11), and unfortunately, it no longer works.
Depending where I invoke bjam, object files are written in different
directories. Invoking bjam in the top directory, a file is generated
If I invoke bjam in a subdirectory, it generates the same file here:
I have spent a hard time understanding why. My guilty is the function
determine-output-name, which calls determine-target-name.
rule determine-target-name ( fullname : prefix ? : postfix ? )
# See if we need to add directory to the target name.
local dir = $(fullname:D) ;
local name = $(fullname:B) ;
name = $(prefix:E=)$(name) ;
name = $(name)$(postfix:E=) ;
if $(dir) &&
# Never append '..' to target path.
! [ MATCH .*(\\.\\.).* : $(dir) ]
! [ path.is-rooted $(dir) ]
# Relative path is always relative to the source
# directory. Retain it, so that users can have files
# with the same in two different subdirectories.
name = $(dir)/$(name) ;
return $(name) ;
I don't understand why, depending on the fact that the path is
relative or not, the target name should be prefixed by the directory.
2.0-m11 only made: name = $(name:D=)
