+dnl Usage: TL_AC_GXX_INCLUDE_DIR
+dnl
+dnl Set $gxx_include_dir to the location of the installed C++ include
+dnl directory. The value depends on $gcc_version and the configuration
+dnl options --with-gxx-include-dir and --enable-version-specific-runtime-libs.
+dnl
+dnl If you change the default here, you'll need to change the gcc and
+dnl libstdc++-v3 subdirectories too.
