Dartium fails to build on windows


I am trying to build a version of Dartium on windows, but I keep running into a problem.

I am trying to build a Dartium with the proprietary codecs, so I can play AAC codec in an MP4 file, which normal Dartium can’t play.

I am building this on a windows 2016 Datacenter (VM), I have installed Dart 32bit, Visual Studio 2015, with windows SDK, and followed the instructions on: https://github.com/dart-lang/sdk/wiki/Building-Dartium


If you add

#pragma warning disable C4172

at the top of the thread.cc, that should fix the compilation.
