Change unit code for proj 18141-2 19912 19924-5 19935 and projCS 24571 27291-2 29871-2 30200 to reflect the unit changes. (Cont...)(...cont). Change factors b and c from 12 and 39.370432 to 0.304797265 and 1 respectively. Length units 9007-9012 and 9032 replaced by 9039 9063 9043 9062 9042 9040 and 9041 respectively (effectively these have been renamed).
