Errr, no. If I'm following you correctly you are saying the C headers
defined in Annex D are the Standard C library headers refered to above, but
that isnt how I read the standard; given:
17.4.4.1/3
"Header inclusion is limited as follows: The C headers ( .h form, described
in Annex D, D.5) shall include only their corresponding C++ header, as
described above (17.4.1.2)."
I read that as meaning the C headers are distinct from the C library headers
used as a basis for the cname headers, and thus <xxx.h> contains all of
<cxxx>, including the the additional signatures.
