change comilation-flag for only one file

Hello,

In our project, there is one file that needs to be compiled with a lower 
level optimisation as all other files in a release build. The reason is 
that the algorithm in that file looses numeric precision with the 
highest level of optimisation. My question now is: how to achive this 
with bjam?

I have for instance :

lib libfoobar : foo.cpp bar.cpp : <threading>multi ;

I can for instance suppress optimisation on the whole library doing:

lib libfoobar : foo.cpp bar.cpp : <threading>multi <optimization>off ;

However this suppresses optimization for the whole library. So how can I 
only suppress the optimisation in bar.cpp?

Thanks in advance,

toon
