When building media-gfx/inkscape-0.47 with GCC 4.5, the following error occurs: depbase=`echo eraser-context.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\ x86_64-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I.. -I/usr/include/freetype2 -pthread -DORBIT2=1 -I/usr/include/gnome-vfs-2.0 -I/usr/lib/gnome-vfs-2.0/include -I/usr/include/gconf/2 -I/usr/include/orbit-2.0 -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -fopenmp -I/usr/include/ImageMagick -I/usr/include/libwpg-0.1 -I/usr/include/libwpd-0.8 -I/usr/include/poppler -D_REENTRANT -I/usr/include/poppler/glib -I/usr/include/poppler -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/pango-1.0 -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/directfb -I/usr/include/libpng12 -DPOTRACE=\"potrace\" -D_REENTRANT -pthread -I/usr/include/gdkmm-2.4 -I/usr/lib/gdkmm-2.4/include -I/usr/include/giomm-2.4 -I/usr/lib/giomm-2.4/include -I/usr/include/pangomm-1.4 -I/usr/lib/pangomm-1.4/include -I/usr/include/gtk-2.0 -I/usr/include/glibmm-2.4 -I/usr/lib/glibmm-2.4/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -I/usr/include/cairomm-1.0 -I/usr/include/pango-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/directfb -I/usr/include/libpng12 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/gtkmm-2.4 -I/usr/lib/gtkmm-2.4/include -I/usr/include/gtk-unix-print-2.0 -I/usr/include/atkmm-1.6 -I/usr/include/libxml2 -I/usr/include/gtkspell-2.0 -I../cxxtest -I./bind/javainc -I./bind/javainc/linux -Werror=format-security -Wall -Wformat -Wformat-security -W -D_FORTIFY_SOURCE=2 -Wall -g -O2 -MT eraser-context.o -MD -MP -MF $depbase.Tpo -c -o eraser-context.o eraser-context.cpp &&\ mv -f $depbase.Tpo $depbase.Po eraser-context.cpp: In function 'void set_to_accumulated(SPEraserContext*)': eraser-context.cpp:752:55: error: 'r' was not declared in this scope This error does not occur with GCC 4.4 or earlier. In GCC 4.4 and earlier, and in the original C++ standard, struct A { struct B {}; }; A::A::A::B::B::B::B::B myVariable; is a perfectly valid declaration of a variable of type A::B. In GCC 4.5, and in the current C++ standard, A::A is A's constructor, not the type A. (The above explanation was found here: http://code.google.com/p/seccompsandbox/issues/detail?id=1 )
