Note that I didn't say that _using_ bitfield in gpg was a bad idea, but
_passing_ it [to a variadic that expects a long] was.

Yes. I agree that breaking gpg build isn't nice, but the code already
relied on undefined behavior. Therefore I think that this is a corner
case and the call should be fixed to pass a long. New libcurl version
will likely provide a define to skip the typechecking macro, but adding
a long cast or flags.someflag ? 1L : 0L is still the preferred solution

Yes, this is a known issue...
