Can you check if the last version of pynac still gives these errors? 

http://trac.sagemath.org/sage_trac/ticket/7029

I merged some patches from GiNaC to address those issues a while ago.
Apparently the MSVC compiler also complains about them.


BTW, now that cephes is a standard package, changing a few lines in
sage/symbolic/pynac_cc.h should be enough to fix #9162.
