Re: 7.1.4p2 vs. Annex J

Show all headers | View raw

J.2 is informative, and the part you quoted refers to normative text
7.1.2. In the current C2X draft N2479, the relevant sentenceg in 7.1.2 is:

"If used, a header shall be included outside of any external declaration
or definition, and it shall first be included before the first reference
to any of the functions or objects it declares, or to any of the types
or macros it defines."

So clearly, the undefined behaviour does not happen when the header is
not used at all.
