[Cfp-interest 2946] Re: TS-4 revision using new headers

[Jim Thomas]

In response to issues Rajan raised about draft cfp4rh-20231105, I suggest the following changes:

To 5.1 append the paragraph:

	These macros shall be regarded as conditional feature macros (C23 6.10.9.3) and the corresponding features as conditionally normative features of C.

Replace 5.3 with:

If the implementation defines one of the feature macros in 5.1 then the implementation provides the corresponding header specified in this document. The header and its use follow the general specification in C23 7.1 for the Library as though the header were added to the list of standard headers in  C23 7.1.2 and the relevant specification in this document were added as a subclause for standard headers in C23 Clause 7.

CFP is proceeding in two steps: (1) produce a TS-4 revision draft that addresses all the other known issues including ones from WG 14 and deliver that as an N-document; (2) try to rework that document to use headers and if successful deliver that as a subsequent N-document to replace the previous one for advancement.
