Hello all, I wrote: I'm embarrassed to admit that the integration of mini-gmp into guile has long been waiting on my pending numerics patches. I'll try to get going on this (and some other things) for the 2.0.8 release. http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10519#8 I've posted a new

bug#10519: guile and (mini-)gmp

Hi, A ping on this bug on getting Guile to have the possibility of using an embedded copy of mini-gmp. 1. What is the status of mini-gmp? I understand that you use it in GMP itself, so hopefully mini-gmp is in a good state, upstream. 2. Has anyone looked at getting mini-gmp into Gnulib?

Greets, Thanks for working on this, Niels, and thanks for following up on it, Mark. It's great to have such knowledgeable folk working on this problem. One suggestion, if it's possible: it would be great if mini-gmp could make it to be part of gnulib at some point. That's probably the easiest

bug#10519: guile and (mini-)gmp

Hi, I'm hacking on something called mini-gmp (see http://gmplib.org:8000/mini-gmp/). This is inteded to be a small and simple implementation of a GMP subset, suitable for programs which needs bignums, but which don't use very large numbers or very high performance. (I aimed for mini-gmp.c to be
