Re: Build properties algorithm

Hello,

I've just updated to the latest cvs to try this and the other bugfix 
related to IMPORT (thread "Custom main target").

There seems to be some problem related to the new build properties 
algorithm. After the upgrade my system libraries no longer work :(.
----------------------------------------------------------------------
d:/software/boost-build-cvs/v2/build\targets.jam:513: in generate-really 
from module object(main-target)@5
error: failed to build /cppunit with properties <arit>double 
<debug-store>object <debug-symbols>on <define>ARIT_DOUBLE 
<exception-handling>on <hardcode-dll-paths>false <inlining>off 
<link-runtime>shared <link>static <optimization>off <os>NT 
<profiling>off <rtti>on <runtime-debugging>on <stdlib>native 
<threading>multi <toolset-msvc:version>6.0 <toolset>msvc <variant>debug 
because no best-matching alternative could be found
----------------------------------------------------------------------
The cppunit library is defined as follows in user-config.jam:
----------------------------------------------------------------------
project.initialize $(__name__) ;
project site-config
: usage-requirements <include>d:/software/cppunit-1.8.0/include ;

lib cppunit : : <name>cppunit60 <variant>release 
<toolset-msvc:version>6.0 <search>d:/software/cppunit-1.8.0/lib ;
lib cppunit : : <name>cppunitd60 <variant>debug 
<toolset-msvc:version>6.0 <search>d:/software/cppunit-1.8.0/lib ;

lib cppunit : : <name>cppunit71 <variant>release 
<toolset-msvc:version>7.1 <search>d:/software/cppunit-1.8.0/lib ;
lib cppunit : : <name>cppunitd71 <variant>debug 
<toolset-msvc:version>7.1 <search>d:/software/cppunit-1.8.0/lib ;

lib cppunit : : <name>cppunit <variant>release <toolset>gcc 
<search>c:/msys/1.0/local/lib ;
lib cppunit : : <name>cppunitd <variant>debug <toolset>gcc 
<search>c:/msys/1.0/local/lib ;
-----------------------------------------------------------------------
First thing that hits me is that there are both <arit>double and 
<define>ARIT_DOUBLE in the build request. That's strange because <arit> 
is defined as follows in my project-root.jam:
-----------------------------------------------------------------------
feature arit
: double float fixed debug
: propagated link-incompatible composite symmetric
;

feature.compose <arit>double : <define>ARIT_DOUBLE ;
feature.compose <arit>float : <define>ARIT_FLOAT ;
feature.compose <arit>fixed : <define>ARIT_FIXED ;
feature.compose <arit>debug : <define>ARIT_DEBUG ;
------------------------------------------------------------------------
My expectation would be to have it expanded for the real build request 
so only <define>ARIT_DOUBLE would be present.

So for now I'll have to downgrade until this is resolved :(.
