Zeus for Windows uses ctags as it's source of tags information 
and this is used to provide a limited form of auto-completion. 

But unfortunately  providing good intellisensing is far from 
simple. The reason is the information produced buy ctags is 
class based and looks very nice in a class browser window.

But the programmer works with instances of those classes and
the hardest part of implementing good intellisensing is 
correctly identifying to which class the current instance 
belongs. 

This is not as simple as it may seem as it depends a lot on 
the current scope. For example a local variable, a global 
variable, and a member variable can all have the same name
yet all be of different class. But of the three only one will
be correct and which one depends on the current scope.
