Looks like mingw supports 3 types of exception handling. LDC usually tightly coupled with mingw version, you shouldn't try it blindly, but follow installation instructions instead.

What is required is Dwarf 2 EH and a working TLS implementation. The latter is the reason for the "recent version of mingw-w64" requirement, because I fixed the implementation there a year ago or so. No idea if the mingw.org people have gotten their act together since. That being said, it still makes sense to try a known good version first, as LDC exercises quite a large part of the compiler/runtime features, some of which aren't needed in more wide-spread use cases (for example native TLS).

I wanted a binary download install process. LDC came down fine, but it was then a question of getting MinGW-w64. The MinGW-w64 installer only offers seh and sjlj as options it doesn't offer dw2. I probably would have read the README eventually, but I wasn't in the frame of mind of doing this: I just wanted to test something on Windows quickly and give the machine back. I am therefore a bad sample for worrying about making things clear! :-) On Linux, I happily build LDC from a Git repository clone, I have even got it all working on OSX as well.

SEH was patented, so llvm doesn't support it.That has changed.

Avoiding things covered by patents *and* writing code that actually does anything useful is NOT REALISTICALLY POSSIBLE. The SEH patent is just a red herring here.
