You could have:

flags msvc.compile CFLAGS <variant>debug : /D_DEBUG ;

but that wouldn't add it to the response file and is limited to the specific 
toolset. It would be useful to do something like:

property.add <variant>debug : <define>_DEBUG ;

to allow helper toolsets (such as SDKs) add additional properties in a 
generic way.
