   There are several properties you might use related to this:
     <runtime-link> shared/static
     <threading> single/multi
     <runtime-debugging> on/off

   For raw tool option passing:

   For the debug/release variants - see the <variant> feature, and since
its values are implicitly recognized, just stating debug or release or
both on the command line should be recognized correctly as well.

   The fastest way to find an answer to all this is to just look at
msvc.jam. For example, lines:

> toolset.flags $(toolset).compile CFLAGS $(conditions)/<runtime-debugging>off/<runtime-link>static/<threading>single : /MT ;
> toolset.flags $(toolset).compile CFLAGS $(conditions)/<runtime-debugging>on/<runtime-link>static/<threading>single : /MTd ;

state that when you have runtime-link static & threading single
specifying specifying runtime-debugging off will add the /MT option to
the compiler command line while specifying runtime-debugging on will add
/MTd instead.

   Hope this helps.
