#11551: Pari segfault on Sage startup in Cygwin

------------------------+---------------------------------------------------
In both Windows XP and Window 7 it is now possible (again) to build Sage
on Cygwin. However, Sage has a segmentation fault in Pari upon startup.
This happens in initalizing the Pynac i (`init_pynac_I` in
sage/symbolic/pynac.pyx), but the final thing is that the mpfr number
1.00000000000 causes the segfault upon running the `._pari_()` method.
Suggestions as to why that would be - and a potential fix - are welcome.
----
Interestingly, one can spend hours using `sage -gdb` to recreate exactly
what happens in XP, but it just falls out for free in a normal Sage
backtrace in Windows 7.
