Here is a small patch to allow the special maths functions that came in with
TR29124 into C++17 in Jacksonville.
I am leaving the TR29124 access with __STDCPP_WANT_MATH_SPEC_FUNCS__ for C++
< 17.
I added the SD-6 feature macro:
#define __cpp_lib_math_special_functions 20163L
Passes testing on x86-64-linux.
OK?
ENOPATCH ;)

Arrgh!

Pull C++ Special Math into std for C++17.
* include/bits/specfun.h: Allow special functions for C++17;
define __cpp_lib_math_special_functions.
* include/c_global/cmath: Allow special functions for C++17.
* include/c_compatibility/math.h: Ditto
