This fixes Mantis bug #557. compiler/module_qual.qualify_items.m: When module qualifying checked type, inst and mode definitions, - qualify the checked definition as appropriate to the module section where the definition's body is, and - do not discard any error messages generated by this process in favor of the error messages (if any) generated by qualifying the source definitions the checked definition was constructed from. The source of the Mantis #557 bug was that in a type definition, an argument type was (a) uniquely qualifiable in the interface section, but (b) was ambiguous in the implementation section, due to an extra module import being visible in the implementation section. The first change above fixes this bug. The second change is there to ensure that if we set the flag that says we found a non-uniquely-module-qualifiable type, inst or mode name, the error message we generate when we do that won't be discarded. The second change also means that such errors get two error messages generated for them, but since we always sort error_specs and any remove duplicates, this is not a problem. tests/hard_coded/bug557.{m,exp}: tests/hard_coded/bug557_helper.m: The test case for this bug, with a comment explaining the bug. tests/hard_coded/Mmakefile: Enable the new test case.
