Out of curiosity, I had a quick look at the patches as posted to the
guile devel list.
For the small integer gcd code, you may want to ha

Great, thanks! And sorry for not following more closely...

FYI, I've pushed patches to Guile's git repository (stable-2.0 branch)
which eliminate the known obstacles to mini-gmp integration.

The version bundled with gmp-5.1.1 is fairly solid. The first release,
with gmp-5.1.0, had some severe bugs. Testsuite has been improved

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

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?

I guess you can do whatever you want in gnulib. But it should be

If that's really needed, it can be substituted with something like

It's main home will be the GMP repo and distributions. But that doesn't
exclude that it's also copie

It's main home will be the GMP repo and distributions. But that doesn't
exclude that it's also copied into gnulib, if that's convenient.

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

I'm looking into this. I found that the GMP interface has one awkward
feature: The current allocation size must be passed as an argument to
the free and realloc functions. See

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
