--- Comment #41 from Dodji Seketeli <dodji at gcc dot gnu.org> 2011-10-17 10:26:42 UTC --- Most of the work done in the patches in attachment was finally checked in to support tracking locations across macro expansions. The summary of the submission is at http://gcc.gnu.org/ml/gcc-patches/2011-10/msg01461.html. This bug is still not fixed yet, though. To properly fix it, I need to change the FEs so that declspecs have their own location. With that, I'll modify the patch that I sent to http://gcc.gnu.org/ml/gcc-patches/2011-09/msg01043.html. For the record here is the end of the email thread that gives insight into this: http://gcc.gnu.org/ml/gcc-patches/2011-10/msg00264.html.
