Dear all,
During a recent package submission, we were highlighted that some lines
in our configure script didn't follow the correct syntax. The lines
looked like this:
x=$(($y/10))
We were indicated at the time that this is because the statement does
not use Bourne shell syntax, which is absolutely true, and also that the
manual warns about this, which is true again. So far everything

For what it's worth, Autoconf does not assume that arithmetic
expansion will be available. Instead, it emits the following shell
code:
if ( eval 'test $(( 1 + 1 )) = 2' ) 2>/dev/null; then
eval 'func_arith ()
{
func_arith_result=$(( $* ))
}'
else
func_arith ()
{
func_arith_result=`expr "$@"`
}
