Hi, I have a comment about the generic-reloptions patch.

You use struct relopt_gen (and its subclasses) for the purpose of
both "definition of options" and "parsed result". But I think
it is cleaner to separete parsed results into another struct
something like:
struct relopt_value
{
const relopt_gen *which;
bool isset;
union
{
bool val_bool;
int val_int;
double val_real;
} types;
};
the ariables 'isset' and 'parsed_val' are not used in definition, AFAICS.
