Ah, it seems I forget some of the magic spells. The line:

  flags msvc.compile CFLAGS : /Op ;

Add /Op to command line for *all* msvc versions, not just for the current one. 
You have two non-8.0 versions, so the option is added twice and shows twice 
in all msvc compilers.

I've just comitted change of that line to:

  flags msvc.compile CFLAGS $(condition) : /Op ;

which should fix this. I've tested on Linux with "bjam -n", can you try again 
on real msvc?

Thanks,
