That's pretty much what my c_legacy headers did, only using macros
defined and undefined.

I checked the archives and realize i never posted details on my c_legacy
headers design.  I stopped work on it when I came up with what I thought
was a much better idea (I was at the point of ironing out test case failures).
I'm imagining everyone scrambling like a disturbed anthill to get 3.0 out the
door, but when things settle down I can dig up the design to give one more
choice for the Most Satisfactory Solution to the chronic C header problem.
Ping me.
