US 52-122 28.7.1 [cmath.syn] Fix signature of nexttoward

[wg21bot]

The signature of nexttoward was incorrectly changed by P1467. The second parameter should be long double, not floating-point-type.

Proposed change:

Modify the declaration of nexttoward in 28.7.1 [cmath.syn] as follows:

constexpr floating-point-type nexttoward(floating-point-type x,
  floating-point-type**long double** y);

This is LWG 3790 and the proposed change is not what we want.

This smells like Library territory.

LWG 3790 has been updated with the solution discussed by LWG.
