+source: http://patchwork.ozlabs.org/patch/129800/
+Upstream-Status: Submitted
+
+ChangeLog
+ * Makefile.in (gcc_gxx_include_dir_add_sysroot): New.
+ (PREPROCESSOR_DEFINES): Define GPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT.
+
+ * cppdefault.c (cpp_include_defaults): replace hard coded "1" with
+ GPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT for "add_sysroot" field.
+
+ * configure.ac (AC_SUBST): Add gcc_gxx_include_dir_add_sysroot to
+ control whether sysroot should be prepended to gxx include dir.
+
+ * configure: Regenerate.
+
+Hi, this is a follow up for issue "http://codereview.appspot.com/4641076".
+
+The rationale for the patch copied from previous thread:
+=======================================
+The setup:
+
+Configuring a toolchain targeting x86-64 GNU Linux (Ubuntu Lucid), as a
+cross-compiler. Using a sysroot to provide the Lucid headers+libraries,
+with the sysroot path being within the GCC install tree. Want to use the
+Lucid system libstdc++ and headers, which means that I'm not
+building/installing libstdc++-v3.
+
+So, configuring with:
+ --with-sysroot="$SYSROOT"
+ --disable-libstdc++-v3 \
+ --with-gxx-include-dir="$SYSROOT/usr/include/c++/4.4" \
+(among other options).
+
+Hoping to support two usage models with this configuration, w.r.t. use of
+the sysroot:
+
+(1) somebody installs the sysroot in the normal location relative to the
+GCC install, and relocates the whole bundle (sysroot+GCC). This works
+great AFAICT, GCC finds its includes (including the C++ includes) thanks
+to the add_standard_paths iprefix handling.
+
+(2) somebody installs the sysroot in a non-standard location, and uses
+--sysroot to try to access it. This works fine for the C headers, but
+doesn't work.
+
+For the C headers, add_standard_paths prepends the sysroot location to
+the /usr/include path (since that's what's specified in cppdefault.c for
+that path). It doesn't do the same for the C++ include path, though
+(again, as specified in cppdefault.c).
+
+add_standard_paths doesn't attempt to relocate built-in include paths that
+start with the compiled-in sysroot location (e.g., the g++ include dir, in
+this case). This isn't surprising really: normally you either prepend the
+sysroot location or you don't (as specified by cppdefault.c); none of the
+built-in paths normally *start* with the sysroot location and need to be
+relocated. However, in this odd-ball case of trying to use the C++ headers
+from the sysroot, one of the paths *does* need to be relocated in this way.
