Category: Normative change to intent of existing feature

Committee Draft subsection: 7.7.10.3

Title: The remquo function is confusing and hard to implement


Detailed description:

This will be extremely hard to implement on many architectures, will be a
fruitful source of obscure bugs, and will baffle most users.  It also
creates havoc in 7.9.1 Type-generic macros.  I suggest making the quo
argument 'double *' and replacing the last sentence by:

    In the object pointed to by quo it stores the remainder as defined
    under the remainder function (see 7.7.10.2).

If this is not done, it needs to be excluded from the list of type-generic
macros in 7.9.1.
