This is probably editorial.
The following items should be removed from the draft, because they're redundant with Annex D, and they arguably make some *.h headers non-deprecated:
[stdinth] (regarding <stdint.h>)
[fenv] (regarding <fenv.h>
Line 3 of [c.math] (regarding <tgmath.h>)
[cmplxh] (regarding <complex.h>, though the note in this subclause is not redundant)
