What has become of John Maddock's implementation of the Remez algorithm for Chebychev approximation?

Until v1.53, Boost Math had doc pages [1,2] on the Remez algorithm.
This algorithm [3] computes the coefficents of the Chebyshev polynomial
that approximates a given function. Page [2] refers to actual code
in directory libs/math/minimax. This code can still be found on
GitHub [4], but maintenance status and dependences are unclear.

Anybody around who knows anything about this code?

Kind regards, Joachim
