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, 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.
