math.h:nexttoward missing in cygwin

- Subject: math.h:nexttoward missing in cygwin
The math.h nexttoward function [1] in math.h is not available in
Cygwin gcc (but does exist under the ming compiler in Cygwin). It's
not clear to me though when nexttoward is preferred over nextafter.
Boost calls nexttoward a legacy function [2].
