I have another idea.  I suggest instead generating a table of
defaults, and adding a cf_default[] pointer to struct cfdata.  Then
you access the defaults using `cf->cf_default[FOOCF_LOCATOR + n]'.

There only needs to be one default table per attribute, of course, so
it doesn't have to take much space at all.
