I have a related question, though. There are quite a number of -f options

Most such options are meaningless in the negative form (and should have
RejectNegative added), but there are exceptions; -fno-builtin-<function>
is a meaningful option, in particular.
Yes, I was pretty sure that there were options where an argument was
indeed meaningful with -fno-whatever. You could always handle that by
an explicit -fno-whatever entry in the .opt file or some new option
attribute that is the inverse of RejectNegative, but I'd rather not have
to touch actual code for handling options for this project.... just get
the .opt files into better shape regarding options we don't have to
write documentation for so it's easier to track real omissions in the
manual.
