Right, I had to do that with m4rie also.

Also an issue with m4rie.  The problem is that there is now a
namespace involved, so you have to change all instances of GFqDom to
Givaro::GFqDom.

Okay, I'll look through it over the weekend.  If you have parts that
you think are ready to go, the best thing to do is file a bug.  That
way the patches won't get lost or forgotten.

Okay, we can pursue that path.

Incidentally, looking at the latest Singular release, I see that it
can use flint if it is available.  We have flint 1.6, which I kept
deliberately because Sage's flint package is at 1.5.0.  However,
Singular wants flint 2.3!  What should we do there?  Is there a part
of sage that really needs the older flint version, or should I upgrade
it for Singular?
