According to the EDG front end docs neither Koenig lookup nor for scoping can
be detected through a macro. Thats why I proposed a comment, just to make the
user know that he can do somthing to remove the deficiency.

I am quite sure that almost all users will use the default setting, as these
conformance issues are not mentioned in the icl user guide. On the other hand
the compiler status should reflect whether a certain lib can be used with a
certain compiler. Think about someone starting a project from scratch. He
might get the wrong impression.

I would aim for something like the most conforming usable compiler setting.
Those who know VC6 and the disable microsoft extensions switch might have an
idea what unusable means. Non default switches should be clearly documented.
