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.
