Unified error handling - Githubissues

I have a use case that requires error handling, however I currently have to do target-os dependent conditional compilation to properly handle errors on both linux and windows.

Here's a practical example:

#[cfg(not(target_os = "windows"))]
fn is_no_such_var_error(err: &std::io::Error) -> bool {
    err.kind() == std::io::ErrorKind::NotFound
}

#[cfg(target_os = "windows")]
fn is_no_such_var_error(err: &std::io::Error) -> bool {
    err.kind() == std::io::ErrorKind::Other && err.raw_os_error() == Some(203)
}

I'd appreciate if you add support for unified error type for determining when the variable is not defined.

PS: I'm working on this, come take a look if you're interested.
