[V2] Some usage results

Hi !

I've tested library dependencies and the basically work. I've got my 
external libx and add dependencies to it by specifiying 
<dependency>@/libx/libx (test case attached, as usual ;-))

But I made an interesting observation: In my program, I need to have 
three files compiled and linked _without_ optimization. I've simulated 
this in the example by compiling bjam/main/liba with <optimization>off.
When I bjam --v2 bjam/main, I end up with libx recompiled _without_ 
optimization. Of course bjam correctly updates the "normal" libx, too.

To test this further I've added a dependency to Boost by adding a 
use-project/dependency pair to bjam/main/Jamfile. Then I end up with 
all boost libraries compiled with
gcc/release/stdlib-stlport/threading-multi/
and 
gcc/release/optimization-off/stdlib-stlport/threading-multi/

My question is: Is this a bug or a feature ? If this is the correct 
behaviour, this would mean that I end up with a specialized version of 
every external library. And this would waste lots of disk space.

I've encountered several problems using <dependency>@/boost. First, 
$BOOST_ROOT/Jamfile.v2 has no usage-requirements. I think there should 
be at least <include>. ;-)
Second, it seems impossible to mix Jamfile and Jamfile.v2 names. I tried 
to specify file-order in bjam/main/boost-build.jam using 
JAMFILE = [jJ]amfile.v2 [jJ]amfile ;
but this did not work, bjam V2 is trying to use V1-Jamfiles and V2 
Jamfile.v2 in boost tree in random order. I think this is a temporary 
issue, but annoying none the less.
The only solution was to (re-)move all V1-Jamfiles out of the way. 

The third problem is that I don't seem to have a shared python2.2 
library, but I'll try to get it on monday ;-) Static linking works, of 
course. 

And I would like to know more on the status of the msvc-toolset.
I've tried to compile some projects during the last week, but did not 
succeed. Before I post false bugs again, I'd like to have an 
"inofficial" status.

Yours, 
Jürgen
