1dnl Usage: TL_AC_GXX_INCLUDE_DIR
2dnl
3dnl Set $gxx_include_dir to the location of the installed C++ include
4dnl directory.  The value depends on $gcc_version and the configuration
5dnl options --with-gxx-include-dir and --enable-version-specific-runtime-libs.
6dnl
7dnl If you change the default here, you'll need to change the gcc and
8dnl libstdc++-v3 subdirectories too.
