I think these kind of support for code competition are obsolete and
there are new tools popping out that can make the work much more easier.
For example I have been working for a long time with the clang-LLVM
compiler. Clang is a C frontend and It offers a very easy interface to
do code completition on the fly. It's very impressive the way it works
and it's really fast. I have developed myself a small project where I
integrated the code completition support on a scintilla based editor and
it really takes few lines of code.
If you want I can show the code.
The main problem is whether is a problem for you to have this dependency
