I've figured a working alternative using successive calls to `expr STRING : REGEXP` But then again I notice in the autoconf docs (https://www.gnu.org/software/autoconf/manual/autoconf.html#Limitations-of-Usual-Tools) this: "Don't use length, substr, match and index." Since "STRING : REGEXP" does the same thing as "match STRING REGEXP", does that mean I'm out of luck with this approach, too? _______________________________________________ Autoconf mailing list Autoconf@gnu.org https://lists.gnu.org/mailman/listinfo/autoconf
