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 If you change the default here, you'll need to change the gcc and
dnl libstdc++-v3 subdirectories too.
