Hi Roland,

I suggest you start wtih Boost.Build V2, and then read this part of docs:

   http://boost.org/boost-build2/doc/html/bbv2/advanced/targets.html#id2572452

the example there talks about platform-dependent files, only the "platform" 
there is not OS, but compiler. Replacing <toolset>XXX with <os>XXX should do 
the trick for you.

You can also use the 'alias' rule to your advantage:

   lib thread : universal_source.cpp platform_sources ;
   alias platform_sources : a.cpp : <os>NT ;
   alias platform_sources : b.cpp : <os>LINUX ; 

HTH,
Volodya
