What we need is some concrete use cases of toolset inheritance.
Well, to begin with, it's possible to have some common.jam, with

toolset.flags common.compile DEFINES <define> ;

then gcc.jam would say

tolset.inherit-flags common ;

to reuse the first flags declaration. Looking at the V1 cwpro8-tools.jam, it
seems like in V2 it would contain:

toolset.inherit-flags metrowerks ;

In the second case we'd also need to inherit the rules/actions. Maybe, there 
should be

toolset.inherit metrowerks ;

which would bring everything (rules + actions + flags)?
