Re: [PATCH 2/2] gnu: Add Mlucas.

[Andreas Enge <andreas@enge.fr>]

Hello!

I must admit I was put off looking at this patch by the addition of the
flags system, of which I do not understand the justification. Basically,
it seems to be an additional layer on top of what we already have in
our different build systems. We have #:configure-flags and #:make-flags,
and in extreme cases we can set environment variables such as CPPFLAGS
and so on in an additional phase. Commonly used flags can be added to the
build systems once and for all, for others, my impression is that we already
have the mechanisms for doing it on a per package basis. Which problem does
this part of the patch solve?

It should go to algebra.scm, which regroups tools of symbolic, exact
computation (whereas maths.scm contains tools for numerical computation).
