It's also important not to exclude Windows, which sometimes is missing some things that are otherwise universal. Autoconf can't probe on Windows *directly* (without using one of the UNIX-like portability shells, which often provide the missing bits as well), but the fact that Autoconf generates the conditionals (in config.h for example) is still extremely useful in combination with a hand-written config.h.win that's used by Windows MSVC builds. (ssize_t was the thing I ran into most recently that Windows doesn't have but which is otherwise universal and required by POSIX.) -- Russ Allbery (rra@xxxxxxxxxxxx) <http://www.eyrie.org/~eagle/> _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
