We could return a long long, but I'd rather not go there.  Any app with more 
than 32 arguments probably has too many arguments.  Personally, I'd look and 
see if there's anything we can jettison to get it down to 32.  (Going from 
the hdparm man page, -E is useless, -h is already handled (as --help or -? in 
generic code), -Z is something the kernel should do for us as a quirk on that 
hardware, and -v is the default.)

Another alternative is that if we can't get it down to 32, then a uint flags 
isn't an appropriate return value, which would suggest not using 
getopt_ulflags()...
