Windows build is failing

[WebReflection]

I'm trying to make this repo build-able in Linux, OSX, and Windows.

First two are OK, last one a bit messed up.

Ideally we'll publish to npm precompiled binaries and fallback only if necessary in order to simplify npm usage and installation ... anyway ...

The following happens and I'm not sure how to solve since AFAIK there's no equivalent in Windows for g_source_add_unix_fd

Building the projects in this solution one at a time. To enable parallel build, please add the "/m" switch.
