> On my laptop here at home I only have a version of Sage 4.6 and
downloading the latest version of Sage, plus installing it from source etc
might take a little while.

> I could either send you the updated versions of fmpq_poly.c and
fmpq_poly.h and then let you make a patch from it etc. The only other
change necessary should be a one-line change in line 26 of fmpq_poly.pxd.

4.6. I assume they haven't changed since then?
`fmpq_poly.{c,h,pxd}` haven't changed since #4000 got merged.
You could upload updated files onto `sage.math`, or attach them to another
ticket.
