That's another possibility, but given the way the SANE status codes
are defined at the moment, they could share a 32 bit integer with a
backend-specific status code without any problem. So let's spare some
memory ;)

That'd only require simple macros to build and use the SANE_Status
returned, it's not that nasty or difficult imho ;)
