When adding header guards in a recent patch, it erroneously told me that the header guard name should be WTF_config_h, even though the file in question was not in WTF or even JSCore. Here is the line in question, along with the warning it generated: >> Tools/WebKitAPITest/config.h:25 >> +#ifndef WebKitAPITests_config_h > > #ifndef header guard has wrong style, please use: WTF_config_h [build/header_guard] [5]
