digitalmars.D.ldc - Which mingw-w64 version and packager? Is cygwin's ok?

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?

Even if a recent mingw-w64 package is required, LDC is only 
supported on 32 bit. You can use the version mentioned in the 
wiki (http://wiki.dlang.org/Building_LDC_on_MinGW_x86) - this one 
is known to work. (Every newer build should work, too.)

SEH support and C11/C++11 threading are not yet relevant.

Kai

I forgot: cygwin is not supported!

Yeah, after a few headaches and confusion with Cygwin and even the 
Mingw-builds packages, I decided best to just use the package mentioned 
in the LDC README, even if that pollutes my PATH a bit.

Ok, good to understand that. BTW, the "LDC on 32 bit only" limitation is 
a LDC limitation, or LLVM one?

Well, both. LLVM currently has no SEH support for Windows 64bit 
(a task I am working on). But the runtime libraries also miss 
some support, e.g. nested exceptions on Windows 64bit.
This is all Windows related! There are no restrictions on Linux, 
FreeBSD, ...

Yeah, I know, but my main (and currently only) motivation for trying out 
LDC was actually to have an up to date D compiler with debugging working 
on Windows, without having to use Visual Studio...
