Studying an implementation of cdecl and c++decl, which enumerates all
the parts, but does not define all the properties, may help:
don't forget about such things as incomplete types and tentative
definitions. Some scanning of comp.std.c for thread topics about
definitions and declarations may also help. And you could look at the
GCC front ends for C and C++.
