LOL. This build setting is a path to a file in the source tree. I don’t think there’s a file with either name. But it doesn't matter, because this build setting is meaningless for a target that doesn't build a bundle or a binary with an embedded Info.plist.

This quadruplication is one of the reasons why we don’t define build settings in the .pbxproj file, but rather in .xcconfig files. You may be able to get away with simply changing the Generate Unified Sources target’s configuration file to “None” in the project editor, because the default for INSTALLHDRS_SCRIPT_PHASE is NO. If that doesn’t work, you’ll need to create a new .xcconfig file for this target and add any required settings to it.

OHH, I didn't realize that this list of settings was just custom values. Yeah there none of the settings here are needed. TBH, it shouldn't even be different regardless of the build "configuration".

Yeah, setting it to None seems to have worked. I also got rid of the INFOPLIST_FILE setting. For whatever reason you can't get rid of the PRODUCT_NAME setting. I don't fully understand the implications of its existence but w/e. For JSC it doesn't matter since we don't care about the FEATURE_DEFINES value in the JavaScriptCore.xcconfig but in WebCore the unified source bundler script will. It doesn't really seem worth it to redefine all the values in the xcconfig file just so that we can save 4 lines here but idk how to Xcode.

You won’t need to “redefine all the values” in any case, because you can use #include and because within the same level in the build setting hierarchy, the last definition of any build setting prevails.

Ah, good point.

Would be good to land the patch soon, as it resolves some problems in Apple’s internal build system.

Never mind, I overlooked the commit-queue flag.
