The idea was to use C macros to describe the rules for feature configurations and figure out a way to populate them to the various build systems (potentially using a C precompiler to eval the macros). Some of feature configuration flags does not need to be exposed to the build system these can just be #include-d to the source. I do not think that this is a technical superiors solution but perhaps it worth considering to discuss as it relies on tools and syntax we happened to already agree on and I felt that what might come out of it is better what we have now.
