I just tested with 3.1.6, and there is no error message.  If you
set the locale to C, it works properly.

bash-3.1$ gawk --version | head -1
GNU Awk 3.1.6
bash-3.1$ echo "FOO @" | tr '@' '\203' | gawk '/[\177-\240]/{print;}'
bash-3.1$ echo "FOO @" | tr '@' '\203' | LC_ALL=C gawk '/[\177-\240]/{print;}'
