--- Comment #5 from Andrew Macleod <amacleod at redhat dot com> --- btw, the long term plan is that #include "gimple.h" will get all the basic prerequisites you need to manipulate gimple. And then you just #include any extras your specific task requires. We're just in a transition state this release as we flatten to reconstruct a more sensible modular layout.
