I was curious about this as well and took a look on my Windows machine. It
appears that errno will be set to 'No such file or directory' unless you
explicitly set it before checking it. This is odd, given that the helper script
I wrote worked just fine without this requirement. However, I took a look
through the rest of the codebase and noticed that `errno = 0` seems to always be
declared before this type of conditional check. That did indeed fix the issue -
tests all pass on Windows with this patch. I have not confirmed on freebsd,
though, as a heads up.

Thanks,
Lessley
