I was able to get Cygwin64 to build successfully using 7.4.beta2 + Pynac 0.6.9 upgrade (#21369) + interpreter hack (#19868). I did have an issue with twisted not picking up zope_interface, but I was able to fix it by forcing a reinstall of zope_interface and then building twisted again.
For Cygwin32, I'm stuck at pycrypto (#21236 <https://trac.sagemath.org/ticket/21236>). Best, Travis -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
