I'm not sure what is on your list of remaining issues, but here is mine:

a) A bug in bignumcompare for 64bit Windows. Patch is here:
   http://lists.gnu.org/archive/html/emacs-devel/2018-08/msg00487.html

b) fmod_float has a bug:
   http://lists.gnu.org/archive/html/emacs-devel/2018-08/msg00442.html

c) Extend Fexpt to support bignums. Patch is here:
   http://lists.gnu.org/archive/html/emacs-devel/2018-08/msg00503.html

d) Extend Fceiling, Ffloor, Fround and Ftruncate to support bignums by
   updating rounding_driver.

Please describe any additional issues you have discovered.
