        * pdf/xpdf/pdf-document.cc shell/ev-view.c: Hook things up
        a bit, it works! (sort of)

        * pdf/xpdf/Makefile.am pdf/xpdf/pdf-document.cc:
        Move to .cc since we need to use C++ in the implementation.

        * shell/dummy.cc: Add a CC file to force evince
        to be linked as a C++ program.x
