Compilation error in errors.rs

[ennis]

I get these errors when trying to compile using the latest nightly rustc:

rustc version: rustc 1.6.0-nightly (bdfb13518 2015-11-14)
Platform: Windows 10 x64

Thanks for reporting this! I'm updating nightly rust as we speak and will look into it. I'm assuming you're not getting the errors on beta or stable, correct? I'm not primarily a Windows guy, which is why I'm asking.

[kbknapp]

I just confirmed it and think I know what the fix is - once it's patched I'll update crates.io to 1.5.2 👍

[ennis]

Thanks for your quick response! FYI, the same error happens on stable (1.4.0)

[kbknapp]

#346 fixes this, once it merges I'll put out the new version on crates.io

[kbknapp]

@ennis this is fixed, and 1.5.2 is out on crates.io. Let us know if you have any other issues 😄
