Proposed resolution:

Change 26.4.7 complex value operations [complex.value.ops] as indicated:

template<class T> complex<T> proj(const complex<T>& x);

Returns: the projection of x onto the Riemann sphere.

Effects: Remarks: Behaves the same as the C function cproj, defined in 7.3.9.4.

Change 26.4.8 complex transcendentals [complex.transcendentals] as indicated:

template<class T> complex<T> acos(const complex<T>& x);

Returns:  the complex arc cosine of x.

Effects: Remarks: Behaves the same as the C function cacos, defined in 7.3.5.1.

Change 26.4.8 complex transcendentals [complex.transcendentals] as indicated:

template<class T> complex<T> asin(const complex<T>& x);

Returns:  the complex arc sine of x.

Effects: Remarks: Behaves the same as the C function casin, defined in 7.3.5.2.

Change 26.4.8 complex transcendentals [complex.transcendentals] as indicated:

template<class T> complex<T> atan(const complex<T>& x);

Returns:  the complex arc tangent of x.

Effects: Remarks: Behaves the same as the C function catan, defined in 7.3.5.3.

Change 26.4.8 complex transcendentals [complex.transcendentals] as indicated:

template<class T> complex<T> acosh(const complex<T>& x);

Returns:  the complex arc hyperbolic cosine of x.

Effects: Remarks: Behaves the same as the C function cacosh, defined in 7.3.6.1.
