Why was this removed? I think it'll break the Windows build. If not, then let's
file a bug about removing this directory entirely.

VC2013 has proper C99 support, and that's the only compiler we use now.

I filed:
https://code.google.com/p/chromium/issues/detail?id=379999
to remove this. Not sure if I categorized it correctly.
