The option is > -fallow-invalid-boz. fortan/lang.opt defines the options > with the RejectNegative annotation. Why is it RejectNegative? Is there some other option that acts as it negative option? If it is just a standalone boolean option, it should have a negative, so that if e.g. one uses -fallow-invalid-boz in $FFLAGS for most of files in some project, but there is a specific one that shouldn't allow it, one can just append -fno-allow-invalid-boz for it to cancel the earlier option.
