This would be unwise because picking the most recent compiler-supported standard will likely break programs on GNU/Linux. Switching from C++98 to C++11 changes the ABI of standard library templates, so it's basically an all-or-nothing choice for the entire system. (Other language changes can break compilation, but these are less obnoxious and easier to work around.) _______________________________________________ Autoconf mailing list Autoconf@gnu.org https://lists.gnu.org/mailman/listinfo/autoconf
