As part of my libstdc++ libhover work I have started accessing the AST
via a new interface: SharedASTJob which was created for this purpose as
answer to a bug I filed upstream to the CDT.
The linux-distros build has recently run into a build problem because I
just checked in the code and this interface is not in the older CDT zip
I am not sure what to do. I can bring in the class into LibHover, but
it has an internal cdt reference. I can also simply comment out the
code for the time-being. It is not in the v200902060802 version which
is the latest version tag, but it is found in HEAD.
