A few issues fixed (hopefully!)

In response to issue #1 I've audited every single use of std::terminate( )/abort( ) (this is why
I keep the codebase small!), and ensured that at the very least, some
form of error message is displayed before any termination, no matter how
unexpected.

I furthermore disabled AVX codegen, now using SSE2 for compatibility.

I'm also providing the debug binaries, for the brave souls who'd like to track down issues, on computers without the Windows SDK. They're heavily instrumented with debugging output, and you can use a tool like DebugView from Sysinternals to view it.

See the summary in faa5e18 for the full description.

If you're not sure which version to download, then download the 64 bit release.
