PR# 20051 EQA_SYSTEM_PATH violates VYCP-4

In class EQA_SYSTEM_PATH we can see:

```eiffel
convert
	make ({ARRAY [STRING_8], ARRAY [READABLE_STRING_8], ARRAY [IMMUTABLE_STRING_8], ARRAY [STRING_32],
		ARRAY [READABLE_STRING_32], ARRAY [IMMUTABLE_STRING_32], ARRAY [READABLE_STRING_GENERAL]})
```

This violates ECMA's validity rule VYCP-4:

```
4. SOURCEs base class is different from the base class of any other
   conversion type listed for a Conversion_procedure in the Converters
   clause of C.
```

Is there a way to make this class compliant with ECMA, or should this ECMA rule be relaxed in some way in order to accept this class?
