Yes, but note that I don't believe there is a "default" omni cpp
completion - only a default c completion (:help ft-c-omni). I'm not
sure whether the C version understands typedefs or not. (I may test
when I get a chance.) Note, however, that if it does support typedefs,
it would require that you pass options to ctags that cause the typedef
information to be output to the tags file.

No problem.
