All the compilers use the type info in order to create the debug
info part of the compiled object. Unfortunately, if the type is not
used, they ignore it. You can take gcc and force it to save the type
info of unused types. Then you can compile any header file and read
its debug info. The only problem would be the C++ templates, because
they usually are not a part of debug info. You can save the precompied
templates somewhere and read them later. Recall that you should run
the compiler with the same options that you use in the project,
because this influences the macro language, struct alignment etc.
A "dirtier" solution can be changing ctags to include the
declarations instead of definitions. ctags has a much simpler parser,
however I'm not sure if the modern ctags can parse C++ files.
