I'm trying to install Sage on Windows 8.1/Cygwin.
I'm getting the following error after make command (found in mpfr-3.1.4.log):
===============================
In file included from exceptions.c:23:0:
mpfr-impl.h:261:4: error: #error "__unix__ is defined and __GMP_LIBGMP_DLL is true"
# error "__unix__ is defined and __GMP_LIBGMP_DLL is true"
^
mpfr-impl.h:264:4: error: #error "Both __unix__ and MPFR_WIN_THREAD_SAFE_DLL are defined"
# error "Both __unix__ and MPFR_WIN_THREAD_SAFE_DLL are defined"
^

This is fixed by http://trac.sagemath.org/ticket/20380, and the issue is also fixed upstream.

However this is not the only open issue with building Sage on Cygwin, currently. I'm working on the other issues as well.
