Ncgen is unable to resolve ambiguous references to an enum constant when two different enums have same econstant name. Solved by allowing more specific forms for econstant references. 1. /.../enumname.enumconstname 2. enumname.enumconstname 3. enumconstname Case 1 is resolved by using the econstant in the specific enum definition. If none is found, an error is reported. Case 2 is resolved by 1. finding an enclosing group with an enum definition with the specified name and containing the specified econstant. If there are more than one, then an error is reported 2. finding all enum definitions in the dataset that have the specified enum name and contain the specified econstant. If more than one is found, then an error is reported. If the above two methods fail, then report an error. Case 3 is similar to case 2, but all enums, irrespective of name are used if they contains the specified enum constant. The ref_tst_econst.cdl test in ncdump is causing ncdump to fail. So there may be yet some problem.
