Comment 1. 

Category: Normative change to existing feature retaining the original intent

Committee Draft subsection: Annex F

Title: The status of __STD_IEC_559_COMPLEX__


Detailed description:

There is a trap introduced by 7.8 Complex arithmetic, but it should be
fixed here.  The current specification allows an implementation to define
__STD_IEC_559_COMPLEX__, but to do something completely incompatible, and
STILL claim conformance because Annex G is merely informative!  I suggest
putting some wording in the introduction of Annex F like:

    An implementation that defines __STD_IEC_559_COMPLEX__ shall implement
    Annex G as if it were normative.
