Looks like there is a Windows compile problem:
https://code.google.com/p/chromium/issues/detail?id=453196

Probably won't get around to that until tomorrow.

Updated to a87de9b, it should compile on Windows now.

I don't believe any gyp/gn changes are necessary since defining
win32_lean_and_mean is already the default in the chromium build.

[davidben, 2015-01-29 20:09:56]

lgtm if it builds

[eroman, 2015-01-29 20:12:50]

Confirmed -- The win8 trybot has already compiled the boringssl files:
