I'm trying to use this Windows build but encountered the following error:
Generating files to arch "x86" and configuration "release"... ERROR at //build/config/clang/BUILD.gn:126:35: Undefined identifier if (clang_use_chrome_plugins && clang_unsafe_buffers_paths != "" && ^------------------------- See //build_overrides/BUILDCONFIG.gn:390:5: which caused the file to be included. "//build/config/clang:find_bad_constructs", ^-----------------------------------------

Same for 'x86' and 64
