[boost] How do I show entire compiler command line when building boost

Hi, I think this is a very simple question, but I can't find the answer in the boost.build or boost.jam documentation... Is there any way I can make the boost build system show the entire command line (including compiler specific options/flags) it uses to compile files and build libraries? I'm having problems with the new serialization library not linking to the right runtime on vc71 and I'd like to see that command line. By default, it seems to only print the name of the compiler it is using. Regards Dennis
