[Bug-gsl] [bug #39713] roots/secant.c "derivative value is not finite" for a good guess

[Brian Gladman]

Follow-up Comment #11, bug #39713 (project gsl):

I'm not objecting to a quick fix but I don't wan't to put a lot of effort into
making a contribution to GSL if we can't also make improvements.  And I
certainly consider that an API that in common situations forces twice as many
function evaluations as are necessary to find a root is in need of improvement
(in fact I really thought that I must be wrong about this and I still hope
that I am).

I am sorry if this is not the right place to discuss such wider issues but I
am new here and I wanted to understand the design as in my experience I have
found it quite dangerous to 'fix' things that I don't understand.

My experience with having a compatibility define in MPIR (a fork of GMP) is
quite the opposite to your own.  But, as you suggest, that discussion is for
another place.
