For this to work with gawk, you will need the --re-interval argument:

--re-interval
     Allow interval expressions in regexps, even if `--traditional' has
     been provided.  (`--posix' automatically enables interval
     expressions, so `--re-interval' is redundant when `--posix' is is
     used.)
