[Curtis Hovey]

We cannot compile the win client on master as of commit c436dc40 and d1b57c20. It last passed with commit af0b88e3.

fix inadvertent removal of npipe.v2

[Nate Finch (natefinch)]

This is just dependencies.tsv getting out of sync with reality. I'm going to fix both that file and the fact that godeps doesn't list npipe in the dependencies by making npipe a dependency of the linux build. This is somewhat unfortunate, given that npipe is *not* a dependency of the linux build, but unless we stop using godeps for dependency management, or fix it, this is the only solution.

[Nate Finch (natefinch)]

added npipe as a dependency for non-windows builds, after a slight modification to npipe so it was *possible* to import it on non-windows platforms.
