How about:
# Work around the problem that "expr 'a' : 'a\(\)'" outputs "0" in QNX.
case $ac_option in
*=?*) ac_optarg=`expr "x$ac_option" : 'x[^=]*=\(.*\)'` ;;
*) ac_optarg= ;;
esac
Anyway, I'm still concerned with the problem of exceeding the maximum
match length. I'm inclined to think we should support prefixes as
long as the user wants, unless we have a very good reason not to do
so. I mean, it's not like it would be too costly to add a sed-based
fallback here. Or would it?
