Comment:

 Replying to [comment:26 nthiery]:
 > When applying the sage-combinat queue on sage 4.8.alpha0, we got a
 compilation error on universal_cyclotomic_field_c.pyx, most likely due to
 the updated cython (#11761)

 My patch seems to fix the problem. At least, when one uses the new Cython
 spkg and applies the combinat queue up to and including Christian's patch
 and adds my patch as well (which is also in the combinat queue, I think),
 then sage builds and starts.

 Note that the my patch does not add the new  Cython as a dependency - it
 should run with the old Cython as well.

 However, I already get a doctest error in `devel/sage-
 combinat/doc/en/thematic_tutorials/sandpile.rst`. Now it is needed to test
 whether this error is due to the patches from here, or due to some other
 patch in the combinat queue.

 Since it is not sure whether THIS ticket is the culprit, and since it
 builds with the new cython, I am promiting it to "needs review".


 Apply trac_8327_universal_cyclotomic_field-cs.patch
 trac_8327_universal_cyclotomic_field_new_cython-sk.patch
