[V2] Problems with setting <exception-handling>off with msvc

Hi !

I've finally taken some time to analyse my remaining NT problems.
Here's the first:

Due to some 3rdparty library, I've got a project to be built with
<exception-handling>off

This leads to 

e:/libraries/boost_cvs/tools/build/v2/build\feature.jam:669: in 
expand-composites from module feature
error: explicitly-specified values of non-free feature 
<asynch-exceptions> conflict
error: existing values: off on
error: value from expanding <asynch-exceptions>on : (x:G=)

(full trace in exception.txt attached)

This boils down to Boost.Test,
which contains 

alias minimal : : : :
<toolset>msvc:<asynch-exceptions>on

which Boost.Build tries to build, because it is not explicit.

The attached patch (Jamfile.v2.diff) corrects this.

When compiling another project I get (shortened output from bjam -d+2)

msvc.compile.c++ ..\..\..
\build\xxx\msvc-7.1\develop\asynch-exceptions-on\baseio.obj

call "c:/Programme/Microsoft Visual Studio .NET 
2003/Vc7\bin\vcvars32.bat" > nul 
cl /Zm800 -nologo 
-TP /Zi /Ob2 /GR /MD /Zc:forScope /Zc:wchar_t /Ogity /O2 /Gs /EHs /EHa  
-wd4675 /EHc- /WX @"..\..\..
cl : Command line warning D4025 : overriding '/EHs' with '/EHa'
baseio.cpp

This is clearly a misconfiguration and also fixed by the patch.

Yours,

Jürgen
