AFAICS there's not a single use of sd_flags.h that doesn't come with
its own SD_FLAG definition, so I suppose this should be:
#ifndef SD_FLAG
# error "Should not happen."
#endif
?

BTW., is there any particular reason why these need to be defines with
a manual enumeration of flag values - couldn't we generate
auto-enumerated C enums instead or so?
