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