True. Additionally, some of those strange macros are just interpreted
as language keywords by the parser.

That is not exactly what we want, I think. Currently, HOC parses
things file-by-file, so we do NOT want to follow #include directives.
We might just process the line pragmas from CPP to keep track of where
things came from, OTOH.

There is "cpphs".
As a quick solution, I'd say we run the HOC InterfaceGenerator over
the 10.4 SDK in /Developer/SDKs/ (which has all the "old" headers).
I'm still working on cleaning up my InterfaceGenerator rewrite (I
didn't have enough time to finihs last weekend, so maybe next weekend,
but at least I'm motivated now). I think any more more elaborate
improvements to the interface generator should be based on that
instead of my old code.
