I'm usually writing bug reports and feature requests to this forum.
Now, I would like to share a little good news, a great feature that can be used for a trick. 
I'm working with a large code base, that creating a cParent typedef automatically for all class, defining it's parent class.
This cParent is defined by a trick based on the order of header compiling. It is great, because working on VS and GCC also.
But VAX is parsing headers in a different order (sequentally, and not recursively, like compiler does). I have explored that VAX understands __super (MS specific stuff), which is recognised as a parent class.
So, I put this line into VAX's stdafx.h
#define cParent __super
...and VAX now understands our cParent typedef (so VAX is great 
)
So we have a portabe (not MS specific) cParent AND VAX can understand it also. So goto, find references, etc. working now.
For example:
cParent::Update(); // <-- VAX knows what Update is
I hope may helped someone who faced to the same problem
