Be careful with icc compiler family.
It is relatively frequent to get small differences between gcc and icc
floating (double/float) computations.A specialist of floating point said
that icc build faster programs fro two reasons:
1) Intel knows his processors,
2) they make excessive assumptions on

Hi,
As Jupyter is becoming the default notebook in Sage 8.0, I guess it would
be nice to fix this, otherwise many users could be quite disappointed when
getting such a bad pdf export of their notebooks.

The recent update of #22679 shows that on FreeBSD 11.0 we are down to a
couple of seemingly minor test failures for esoteric features, and a couple
of test failures with numerical noise (also seen on OSX clang builds).
So as soon as #12426 is ready, we can also (re)enable Sage FreeBSD, I think.
Well after realising that in its current state #12426/#22646/#23046
would at least let me try to build sage with the intel compiler,
I just did go ahead and got myself an open source license.
On top of the above tickets I had to patch _2_ packages to finish the build.

Suppose that R is some parent which is contained in the category
Algebras(B) for some ring B, how does one determine B from the parent R?
I am asking because I want to implement a new method in the
ParentMethods of Algebras, which needs to refer to the base_ring of the
category. I feel like Pa
