Which mingw-w64 version and packager? Is cygwin's ok?

[Bruno Medeiros]

I'm trying out LDC for the first time (0.12.1).
I understand a recent version of mingw-w64 is required. I was looking 
at: http://mingw-w64.sourceforge.net/download.php
and I was wondering if the Cygwin versions are good? They seem recent 
enough (based on GCC 4.8.2?), but they don't support SEH and C11/C++11 
threading AFAIK. Is that an issue for LDC?
