As far as i can see CTID_MAX is quite generous.
For our needs I've developed some quick&dirty perl script that runs the
required header files via '${CC} -E'.
Given that we include quite a lot of system headers we reached only like
5k types (estimated based on the last error I saw from one of top header
files, complaining that I'm trying to call anonymous union ##).
So most likely you're doing something wrong (as Mike already pointed out...)
(I can share the script if some one needs it by the way. Quite handy to keep
cdefs in sync with actual headers.)
