Rename _i,_argused to i_,argused_
Thanks Michael Forney for reporting this! We cannot use identifiers
beginning with an underscore, says the C99-standard, section 7.1.3:
"All identifiers that begin with an underscore are always reserved for
use as identifiers with file scope in both the ordinary and tag name
spaces."
We go around this by putting the underscore at the end.
